Abstract

Milled polymers are brought into contact with a liquid which selectively dissolves polystyrene and separates polyolefins from polyethylene terephthalate and from polyvinyl chloride by relative density, and then at least one of the polymers thus separated is converted into products of lower molecular weights. <IMAGE>
