Modified composites based on poly(ethylene-vinyl acetate) and crumb rubber
The blocked macrodiisocyanates (MDI) based on oligodienes with hydroxyl groups and a blocking agent p-quinonedioxyme have been synthesized. The effect of the modifier (blocked MDI) on the physical mechanical characteristics and structural features of composites based on the dispersed crumb rubber and functionalized poly(ethylene-vinyl acetate) were investigated. The effective concentration of the blocked MDI and its influence on mechanical and deformation characteristics of composites were studied.
