Abstract
PURPOSE: To prepare an odorless, harmless vinylidene chloridevinyl chloride copolymer useful as food packaging materials and having excellent thermal stability, by carrying out the polymerization in the presence of tocopherol.
CONSTITUTION: Preferably 0.005W0.1 parts by weight of tocopherol on the basis of 100 parts by weight of the monomer, is added to the system at the initiation of the polymerization of vinylidene chloride and vinyl chloride. A hydrochloric acid- trapping agent, e.g. epoxidized soybean oil, etc., (preferably 0.02W5 parts by weight on the basis of 100 parts by weight of the monomer), is added and the polymerization is carried out to give the objective vinylidene chloridevinyl chloride copolymer.
