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 1):
A transparent article formed of a vinyl chloride graft copolymer, the article prepared by a process comprising:\n forming the vinyl chloride graft copolymer by:\n preparing a graft base by polymerizing monomers, wherein the graft base has a first glass transition temperature; \n grafting a copolymer phase having a second glass transition temperature onto the graft base by emulsion polymerization, to form a vinyl chloride graft copolymer latex including the vinyl chloride graft copolymer; and \n separating the vinyl chloride graft copolymer as a solid from the vinyl graft copolymer latex, \n wherein the first glass transition temperature is lower than the second glass transition temperature, the average particle size of the vinyl chloride graft copolymer is less than 200 nm, and the article has a transmittance of at least 65% as measured according to ISO 13468 for a plate having a thickness from 1.49 mm to 1.74, a haze value of less than 60 as measured according to ISO 13468 for a plate having a thickness from 1.49 mm to 1.74 and measured at an angle of 2 degrees to an axis of irradiation, or a combination thereof.
