PROCESS FOR THE SUSPENSION (CO)POLYMERIZATION OF VINYL CHLORIDE AND PRODUCTS ENTIRELY OR PARTLY CONSISTING OF THE RESULTING (CO)POLYMERS

摘要

The invention relates to the suspension (co)polymerization of vinyl chloride in the presence of a radical initiator and at least a primary and a secondary suspension stabilizer. The present primary stabilizer must be selected from the group consisting of water-soluble, partly hydrolysed polyvinyl acetates and methylhydroxypropyl cellulose. The secondary stabilizer is an N-alkyl gluconamide, preferably N-octadecyl gluconamide.
In their solid state these stabilizers can be satisfatorily handled and their use leads to (co)polymers having few fish eyes and high plasticizer absorption.
