Abstract

1509780 Reducing monomer content of pvc powder HOECHST AG 12 Nov 1975 [14 Nov 1974] 46690/75 Heading C3L A process for reducing the vinyl chloride monomer content of the corresponding polymer powder comprises thoroughly mechanically mixing the powder with water and optionally in presence of other conventional additives and simultaneously heating the mixture to at least 70‹ C. The heating energy may be derived wholly or partly by the energy supplied by mixing. The process may be repeated several times.
