Abstract

1530609 Monomer removal PANTASOTE CO 18 Dec 1975 [19 Dec 1974] 51813/75 Heading C3L The removal of monomer from a suspension, solution or bulk polymerized PVC product is aided by including in the polymerization recipe an alkane and after venting to atmospheric pressure after polymerization excess monomer is stripped by heating to at least 160‹ F. at a pressure of 50-200 mm. Hg. The alkane may have 1-20 carbons, is present in an amount of 0À1-10% based on monomer and is usually also removed during stripping.
