Abstract

PURPOSE: To prepare a useful rigid vinyl chloride resin from the hitherto discarded flexible vinyl chloride resin waste containing a plasticizer, by heating the resin in the presence of a specific amount of acid clay, activated clay and activated charcoal.
CONSTITUTION: 100pts.wt. of a vinyl chloride resin having low softening point and containing 15wt% of a plasticizer (e.g. used films, sheets, etc. of vinyl chloride resin) is compounded with 5W100 pref. 20W80pts.wt. of a compound selected from acid clay, activated clay and activated charcoal, and the mixture is heated to obtain the objective vinyl chloride resin having high softening point and excellent mechanical properties.
