Abstract: | In the case of filled systems based on butadiene-styrene copolymers, it has been shown that the attainment of mobility of kinetic segments in definite temperature regions leads in amorphous polymers to an increase in their strength and reinforcement effect, and also to a change in the morphology of the breakdown surface in these temperature regions. The established regularity has been examined from the point of view of the adhesion theory of reinforcement.Moscow Institute of Meat and Milk Industry.
