Abstract: 
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. It is shown that blocked MDI acts as a modifier in prepared composites and leads to improving of mechanical properties.
