METHOD FOR MOLDING MULTI-PLY POLYMERIC COMPOSITES AND PRODUCT OF SAME.

摘要

process for moulding a plurality of layers of a molded polymer compositions having a minimum number of joint internal faults, and thus, improved properties.the layers are positioned in contiguous relationship and the initiation of polymerization is controlled by selecting catalyst systems which are substantially at the same time start the polymerization in each layer in order to prevent the development of gap junctions in (e) hardening the contact points between the layers.
