ABSTRACT:
The present invention provides novel thermoset copolymers, and methods for preparing same, having both the strength and the thermo-oxidative stability required for high performance, high temperature applications. The copolymers comprise (a) a thermoplastic resin having unreacted phenolic OH groups, and (b) bis-oxazoline monomers which have been modified to have at least one substituent on the oxazoline ring selected from the group consisting of a methyl group, a group having at least a substituent capable of undergoing addition polymerization, and a cyclic group capable of undergoing ring opening polymerization.
