Abstract:
      The curing behavior of MVQ with concentrative crosslinker(polyvinylsilicone oil) was analyzed by dynamic mechanical analyzer.The results showed that,using polyvinylsilicone oil as concentrative crosslinker and DCP as curing agent,the curing period of MVQ compound could be treated as two stages expressed in two first-order kinetics equations with different curing rate constants;by using polyvinylsilicone oil in MVQ compound,the activation energy of curing reaction increased significantly,the curing reaction was difficult to proceed,and then the curing temperature should be elevated.
