The applicability of available methods for the analysis of unvulcanized styrene-butadiene rubber (SBR, formerly GR-S) for organic acid and soap is influenced by the type of coagulation (alum or salt-acid), the type of acid present (fatty acid, rosin acid, or mixed acids), and the presence of carbon black or oil. No single method is universally applicable for the analysis of organic acid and soap, but reasonably unbiased results can be attained by proper selection of the available procedures. The complete-solution procedure for alum-coagulated (AC) SBR has given reasonably good results for organic acid in samples containing mixed acids, while the extraction procedure using aqueous isopropanol-toluene azeotrope (ITA) gives good results for AC samples containing fatty acid only. The complete-solution procedure for SBR coagulated with salt and acid gives less biased results for organic acid and soap than the aqueous ITA extraction procedure, but the latter should be used for all SBR containing carbon black and for estimating oil in oil-rubber masterbatches. Both complete-solution procedures and the ITA extraction procedure can be adapted for the determination of stabilizer and bound styrene. The present ASTM extraction procedure using ethanol-toluene azeotrope is less satisfactory than the other procedures. (Author))

Excerpt from An Evaluation of Certain Methods for the Chemical Analysis of Styrene-Butadiene Rubber Three other methods besides the astm procedure using aqueous eta have been suggested for the analysis of AC rubber. The astm procedure involving the use of anhydrous eta for the analysis of soap and organic acid in SA rubber, although much less biased than the method for AC rubber, is not completely satisfactory either. Consequently, two other methods for SA rubber have been suggested. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
