Abstract:
The invention relates to a method for producing vinyl chloride graft copolymers by emulsion polymerization and to a method for producing mixtures of said graft copolymers. The invention also relates to transparent articles produced using the claimed graft copolymers or mixtures thereof.

Claim (Index 14):
The transparent article of  claim 1  prepared by the process further comprising:\n forming a second vinyl chloride graft copolymer by:\n grafting the copolymer onto the graft base by emulsion polymerization to form a second vinyl chloride graft copolymer latex including the second vinyl chloride graft copolymer; and \n separating the second vinyl chloride graft copolymer as a solid from the second vinyl graft copolymer latex; \n \n forming a third vinyl chloride graft copolymer by:\n grafting the copolymer onto the graft base by emulsion polymerization to form a third vinyl chloride graft copolymer latex including the third vinyl chloride graft copolymer; and \n separating the third vinyl chloride graft copolymer as a solid from the third vinyl graft copolymer latex; and \n \n combining the vinyl chloride graft copolymer, the second vinyl chloride graft copolymer, and the third vinyl chloride graft copolymer, wherein the weight ratio of the graft base to the grafted copolymer base of the vinyl chloride graft copolymer is different than that of the second vinyl chloride graft copolymer and the weight ratio of the graft base to the grafted copolymer base of the third vinyl chloride graft copolymer is different than the vinyl chloride graft copolymer and the second vinyl chloride graft copolymer.
