摘要
This invention pertains to a method to permit the molding of a plurality of plies of polymeric compositions into an integral molded object having a minimum number of internal flaws and, therefore, improved properties. The plies are positioned in contiguous relationship, and the initiation of the polymerization reactions is controlled by selecting catalyst systems which substantially simultaneously initiate polymerization in each of the plies to prevent the development of curing seams at the points of contact between the plies.
