Studies in the epoxidation of natural rubber latices are described. Investigated epoxidation routes include the use of bromohydrin intermediates, hydrogen-peroxide-catalyzed systems, and preformed peracetic acid. The latter reagent allows almost quantitative epoxidation of natural rubber up to high
Natural rubber (NR) latex having up to 54% dry rubber content (drc), stabilized by 1.65-5.0 parts of nonionic surfactant [(fatty alcohol)/(ethylene oxide) condensate type] per hundred of rubber can be acidified by acetic acid to pH ca 4, retaining good aggregative stability. It was shown that this s
