摘要：
The relaxation transitions in gels based on star-shaped block copolymers of butadiene and styrene were studied by the method of DSC. The effects of the content and selectivity of a plasticizing agent on the relaxation transition temperatures and the concomitant changes in heat capacity DeltaC(p) were characterized. The two-phase structure of gels was proven. The segmental mobility of polymer chains in the vicinity of the interfacial polystyrene domain-polybutadiene matrix boundary was found to be different from the mobility of segments within the volume of phases.
