摘要：
The invention relates to a process for the preparation of a nylon block copolymer composition by polymerization of lactam in the presence of a lactam-polymerization catalyst and an activator, characterized in that the activator used is a combination of:1. a high molecular weight lactam-terminated activator with a molecular weight of at least 1500, and2. a low molecular weight lactam-terminated activator with a molecular weight of at most 750.The process according to the invention can, in particular, be used in a reaction injection moulding process, in which liquid reaction component are introduced into a mould where fast polymerization to a moulded object takes place.
