摘要：
A process for preparing copolymers of a mixture of a bis-oxazoline and a polyphenolic compound at improved rate of copolymerization by the inclusion of a catalytic amount of a carbonium ion salt of the formula Ph.sub.3 CX wherein Ph represents a phenyl group and X represents BF.sub.4, PF.sub.6, SbF.sub.6, AsF.sub.6, BPh.sub.4 or ClO.sub.4, is described.
