  A blended polyvinyl chloride based resin composition consisting essentially of 100 parts by weight of a vinyl chloride resin has a chlorine content of from about 50 to about 73 percent by weight, from about 5 to about 12 parts by weight of a flame-retarding agent and from about 1 to about 30 parts by weight of a graft polymer. The blended vinyl chloride based resin composition and products derived therefrom exhibit improved flame-retarding and heat tolerance properties. The blended resin composition and its products also exhibit improved vacum moldability and increased impact resistance. In particular, the blended resin composition and its products emit substantially less smoke and less toxic fumes containing hydrogen chloride. A method to produce the blended vinyl chloride based resin composition including a method of processing moldings by thermoforming is also disclosed.
