- vinylidene chloride copolymers are prepared by an aqueous dispersion polymerization process in which the entire initiator is introduced at the start of the polymerization.

Furthermore, vinylidene chloride copolymers are generally characterized by a relatively high melting temperature, which implies very high processing temperatures. These halogenated copolymers also exhibit relatively low thermal stability and limited flexibility. The relatively low thermal stability which characterizes them causes the formation of significant deposits of degraded materials on the die used during processing.
