Synthesis and thermal study of poly- N-p-substituted phenylmaleimides

Abstract

Poly- N-p-bromomethylphenylmaleimide was synthesized from poly- N-p-methylphenylmalcimide at 80°C in benzene solution using N-bromosuccinimide as a brominating agent with a trace amount of benzoyl peroxide. The alcoholysis, aminolysis and Wurtz reaction of poly- N-p-bromomethylphenylmaleimide were carried out using various alcohols, amines and sodium metal, respectively. The polymers obtained were characterized on the basis of elemental analysis. IR spectra and molecular weight measurements. The thermal behaviour of these polymers was studied by DTA and TG methods and the probable mechanism of degradation and crosslinking reactions are proposed.
