Abstract
PURPOSE: To prepare the titled polymer having excellent thermal stability and relatively low degree of polymerization, by polymerizing vinyl chloride or its mixture with other vinyl monomer in the presence of an alkali metal thioglycolate as a chain transfer agent.
CONSTITUTION: The objective polymer is prepared by adding 100pts.wt. of vinyl chloride monomer or a vinyl monomer mixture composed mainly of vinyl chloride and pref. 0.1W5pts.wt. of an alkali metal thioglycolate, pref. sodium thioglycolate to an aqueous solution of a partially saponified polyvinyl alcohol, etc., and polymerizing the monomer pref. at 45W75°C in the presence of e.g. tertiary butyl peroxypivalate.
