Thesis (M.A.) from the year 2010 in the subject Chemistry - Physical and Theoretical Chemistry, grade: 1, Annamalai University, course: M.Phil/Ph.D, language: English, abstract: Effect of Electron Beam Irradiation on Electrical Conductivity of PVC (Poly Vinyl Chloride) was carried out. characteristics of PVC changes according to the dosage of electron beam irradiation. That is amorphous nature of PVC changes to crystalline and also conjugate double bond and free radicals are formed due to the degradation. The free radicals formed due to scission process in responsible at higher energy radiation. The electrical conductivity of polyvinyl chloride after irradiation slightly increases with electron beam radiation dose. It is due to increase in crystallinity in the polyvinyl chloride after electron beam irradiation and production of free radicals due to scission or crosslinking in PVC.

The electrical conductivity of polyvinyl chloride was measured as a function of temperature over the range 30-70C before and after irradiation with 1.3-Mev gammas. Three orders of magnitude increase in conductivity were observed for the irradiated specimens after a dose of 4.8 x 10 to the 7th power Rads. Scission of the polymer chain as the dominant effect of the irradiation is postulated. (Author).

Polyvinyl chloride (PVC) has been around since the late part of the 19th century, although it was not produced commercially until the 1920s; it is the second largest consumed plastic material after polyethylene. PVC products can be rigid or flexible, opaque or transparent, coloured, and insulating or conducting. There is not just one PVC but a whole family of products tailor-made to suit the needs of each application. PVC is extremely cost effective in comparison to other plastics with a high degree of versatility in end-use and processing possibilities, as the reader will note from this book. It is durable, easily maintained, and can be produced in a large range of colours. As a result PVC finds use in an extensive range of applications in virtually all areas of human activity, including medical equipment, construction applications such as flexible roof membranes, pipes and window profiles, toys, automotive parts and electrical cabling. The PVC industry has also started to tackle some of its end-of-life issues. This practical guide provides comprehensive background on the resins and additives, their properties and processing characteristics, as well as discussion of product design and development issues. There have been, and still are, issues and perceptions over environmental and health acceptance covering vinyl chloride monomer, dioxins, phthalate plasticisers, and lead (and cadmium) based heat stabilisers and these are discussed in depth in this book. This book will be of interest to raw materials suppliers and processors or end-users of PVC, as well as anyone with a general interest in this versatile material: resins and additives properties and testing design issues processing, including post processing and assembly property enhancement sustainable development

This book originated from my Publisher's request for anew, concise account of PVC plastics in terms of their nature, properties, process ing, and applications. There is thus, inevitably, an extensive thematic overlap with my-still relatively recent-PVC Technology (4th edi tion), and I have drawn liberally on that source for a substantial amount of relevant basic material. However, the present book is by no means merely an abridgement of the earlier one: whilst indeed considerably shorter, it is not only comparable in scope and general coverage of the subject, but also contains much new information. I have made a point of again strongly featuring the numerous standards relevant-and in many cases cardinal-to the testing and characterisa tion of PVC materials and products, and to the evaluation of their properties and performance: these standards are an indispensable part of the technology of PVC plastics, and nobody concerned with any aspect of this complex subject should fail to recognise that fact. It is ever a pleasure to express appreciation and thanks where they are due. I am grateful to Dipl-Ing. H. E. Luben of Brabender OHG, Duisburg, FRG, not only for the up-to-date information he provided on Brabender equipment, but also most particularly for his exception ally friendly, helpful attitude in all our contacts, and for the trouble he took to make some illustrations and figures available in the form convenient for direct reproduction.

Research Paper (postgraduate) from the year 2010 in the subject Chemistry - Physical and Theoretical Chemistry, grade: 1, , course: Master of Philosophy, language: English, abstract: Over the past decade a great deal of information has been published about intrinsically conducting polymers, more commonly known as "synthetic metals". The basic interest comes from the fact that these new materials combine the physical and chemical attributes of plastics with the electrical, electronic, magnetic, and optical properties of metals or semiconductors. Poly (vinyl chloride) (PVC) is extraordinarily useful as a commercial material. Among the thermoplastics, it ranks second only to polyolefins in total worldwide production volume. Remarkably, it has achieved this status despite its molecular instability toward heat, an instability that is much more pronounced than those of all its major competitors. In a technological sense, this difficulty has been overcome to a large degree, for otherwise the usage of PVC would never have reached its current level Commercial interest in PVC was first revealed in a number of patents independently filed in 1928 by Carbide and Carbon Chemical Corporation, Dupont and IG Farben. From the present research studies, it is summarized that the characteristics of poly vinyl chloride [PVC] changes according to the dosage of electron beam irradiation. That is amorphous nature of PVC changes to crystalline and conjugate double bond and free radicals are formed due to the degradation. The free radicals formed due to scission process in responsible at higher energy radiation. The electrical conductivity of polyvinyl chloride after irradiation slightly increases with electron beam radiation dose. It is due to increase in crystallinity in the polyvinyl chloride after electron beam irradiation and production of free radicals due to scission or crosslinking in PVC.

This book summarizes the state ofthe art research presented at the Fourth International Conference on Frontiers of Polymersand Advanced Materialsheld in Cairo, Egypt in January 4-9, 1997. This conference follows the successful conferences held in Kuala Lumpur, Malaysia in 1995, in Jakarta, Indonesia in 1993 andin New Delhi, India in 1991. These conferences focussed on the most recent and important advances in a wide range of carefully chosen subject areas dealing with advanced materials, their science and technology and new business opportunities resulting from recent technological advances. As its predecessors, the conference held in Cairo was truly international with strong participation of 488 deiegales representing 37 countries from the USA and Egypt, as weil as Europe, South East Asia, Japan, South Africa and the Middle East. The conference was organized by the Egyptian Academy of Scientific Research and Technology, The Arab Society ofMaterials Science and the State University ofNew Y ork at Butfalo. The stated goals ofthe conference were: • To highlight advances and new. findings in the general area of polymers and advanced materials. - • T o foster global collaboration between the USA, Egypt and other nations in the general field of polymers and advanced materials. • To promote the development of scientific ilifrastructure in this field among the different participating countries, especially in the Middle East. • To create a basisforfuture long-term scientific exchanges between the USA and Egypt, and/or other countries.
