摘要：
During photochemical modification of diene-styrene block copolymers, the polymerization of ethyleneglycol dimethacrylate predominantly proceeds in PS-domains. The phase selectivity of the photochemical process is caused by the accumulation of the monomer in the PS phase. The rules of diffusion of nitroxyl radicals and monomers in mixtures of polymers and monomers, as well as in photochemically modified materials were investigated. The coefficients of rotational and translational of additives in the clastomeric and rigid phases were evaluated.
