Abstract

Used PVC articles, esp. non-sorted food packages, are regenerated by (a) cutting the articles into small pieces, and (b) joining the pieces with a regenerating agent consisting of fresh PVC, a gelling agent, a plasticiser, and a stabiliser in such proportions that a gellable compsn. is produced from which shaped articles can produced. Process yields regenerated PVC with good mechanical properties. Specif., 100 pts. wt. PVC pieces are mixed with 20-30 pts. wt. regenerating agent. The regenerating agent may contain a filter and a blowing agent, and a suitable rubber or acrylic polymer.
