of a vinyl halide resin in a major proportion with a minor proportion of other synthetic resins such as chlorinated polyethylene polyacrylate and polymethacrylate esters polyacrylonitrile and terpolymers of acrylonitrile butadiene and styrene any of the well known plasticizers for vinyl halide resins can be used including dioctyl phthalate dibutyl sebacate tricresyl phosphate and octyl diphenyl phosphate in addition to the ingredients described the stabilized resinous compositions may contain other resin additives such as pigments dyes extenders processing aids fillers and light stabilizers in the amount ordinarily employed for the purposes indicated the stabilized vinyl halide resin compositions may be prepared by any convenient procedure one method is to blend the stabilizer with the vinyl halide resin using plastic mixing rolls at a temperature at which the mix is fluid and to mill the composition on a two roll mill at from 150 u00b0 c to 200 u00b0 c for a time sufficient to form a homogeneous sheet the plasticizer if one is employed and other additives may be incorporated with the stabilizer the stabilized composition may then be removed from the mill in the form of a sheet or film of the desired thickness which may be used as such or subjected to a polishing or embossing treatment the practice of this invention may clearly be.
