✦ Synopsis

Abstracl--Vulcanization of styrene-butadiene rubbers was carried out bv gamma radiation in air. For unloaded unextracted rubbers, the dose required for optimum cross-linking was about 40 megaroentgens (MR). Elimination of foreign materials and stabilizers and also incorporation of filler affected the vulcanization. Loaded samples gave vulcanizates with best complex ph.xsico-mechanical properties for filler content of 50 (phr) and a dose of 30 MR. Evaluation of various fillers has shown that the best properties were obtained with HAF among the black fillers and silica in the case of white fillers.

Different combinations of various multifunctional monomers and halogen co-agents were used to sensitize the radiation vulcanization of styrene-butadiene rubber (SBR). It was found that combinations of various vinyl compounds with hexachloroethane give rise to vulcanizates with considerably better ph

Three different styrene-butadiene, gum rubbers were exposed to ?-radiation doses ranging from 0 to 200 Mrad. The crosslink densities, hardness, and the dynamic mechanical properties were evaluated. All specimens increased in hardness and crosslink density driring radiation. This was reflected in an
