Copolymerization of bis(cyanates) and bis(maleimides). A study of model reaction

Reaction modeling copolymerization of bis(cyanate) of 4,4'-isopropylidenedi phenol and bis(maleimide) was studied using the interaction of N-phenyl cya nate with N-phenylmaleimide as an example. it was shown that the starting r eagents are involved into a complex step-by-step reaction yielding a cycloc hain polymer and a set of polycyclochain oligomers with a variable molecula r mass and composition. It is possible that graft interpenetrating networks are formed under the real conditions of polymer synthesis.
