Abstract

The invention relates to polymerisable double-bond derived polyamides obtainable by reacting the polyamide in an aqueous solution with a compound which contains both a polymerisable double bond and an oxirane ring. These derived polyamides may be processed to provide graft polymers with improved properties.
