Polymers and copolymers prepared by the addition of di-carboxy terminated oligomers to bisoxazines or bisoxazolines.

摘要

Polymers and copolymers containing at least one repeat unit of formula: <IMAGE> in which: - R is a single bond or a hydrocarbon chain, - R' is a hydrocarbon chain containing two or three carbon atoms, - P is the residue of an oligomer <IMAGE> whose solution viscosity, determined in meta-cresol at 30 DEG C and at a concentration of 0.5 g/dl, is lower than 0.50 dl g<-1>. Process for obtaining these polymers and copolymers.
