Synthesis and Properties of Poly(enthionitrile)s and Their Copolymers
Poly(enthionitrile)s and their copolymers have been newly synthesized by reacting p-bis(1-chloro-2,2-dicyanovinyl)benzene(2) with sodium sulfide and bisphenol A by interfacial polymerization technique. the copolymers, which are soluble in organic solvents, possess good thermal stability. These polymers undergo a curing reaction around at 350℃ to give insoluble material and show 80% of residual weight at 500℃ and 60% at 650℃.
