The results of nonisothermal kinetic analysis of the thermo-oxidative degradation in air and in oxygen of the copolymer EVA and nitrile-butadiene rubber (NBR) are presented. It was observed that similar processes take place at thermooxidative degradation in air as well as in oxygen of both investiga

Nitrile±butadiene rubber (NBR) has been blended with polychloroprene (CR) in a weight ratio of 1:1. The vulcanizing systems in the blend formulations were varied to obtain non crosslinked CR embedded in vulcanized NBR and non crosslinked NBR embedded in vulcanized CR. The effects of these two differ
A~tract--The photo-oxidation of butadiene rubber (BR) was studied in detail using films of a commercially available material, containing 33% cis-l,4-, 56°/o trans-l,4and 12% 1,2-vinylic units. The spectral data of the products showed that during photo-oxidation the following functional organic group
