ABSTRACT There are disclosed nylon block copolymers together with a process of preparing such copolymers which will have cross-linking, and which results in a significant improvement of the properties in the nylon block copolymers. Such copolymers are useful as castings, amongst other utilities. The polymer is prepared by reaction of at least one acyl lactam functionalized material and at least 0.02 equivalent of at least one polyfunctional amine where the acyl lactam functionalized material is derived from an elastomeric polymer having a molecular weight between about 200 and about 15,000, where the acyl lactam group is a C3 to C14 lactam derivative of a carboxylic acid, a sulfonic acid, a phospho- acid or a thiocarboxyl derivative of a carboxylic acid and where the amine has a molecular weight of at least 60 and its polyfunetionality is provided by at least 2 primary or secondary amine groups.
