Abstract
Vinylidene chloride polymers or copolymers are stabilized with a mixture of iron oxide and magnesium oxide, preferably in amounts of at least 0.5 part of each per 100 parts of polymer. In an example a vinylidene chloride/vinyl chloride copolymer containing calcium stearate lubricant is so stabilized.
Mixed process for the mass preparation of polymers and copolymers based on vinyl chloride, and polymers and copolymers of improved properties resulting therefrom
