ABSTRACT:
Elastomeric ethylene/alkyl acrylate/1,4-butenedioic acid ester copolymers are stabilized against variations in cure characteristics by reaction of such polymers with amines, perferably during isolation of such polymers. In addition, substantial increase in the molecular weight of such polymers is achieved if the amines are di- or polyamines.
