Abstract
PURPOSE: To produce titled polymer with ease in monomer removal, by suspension- polymerizing a vinyl chlorie type monomer in the presence of a suspension stabilizer consisting mainly of a specified partially saponified PVA and a cellulose derivative.
CONSTITUTION: A suspension stabilizer is obtained by mixing (A) 100pts.wt. of a partially saponified PVA having 0.02W5mol% of carboxylic groups in the side chains, saponification degree 60W80mol%, average polymerization degree 600W 1,500, with (B) 5W120pts.wt. of a cellulose derivative having a 2wt% aqueous solution viscosity at 20°C, of below 1,000cps, such as methyl cellulose and/or a propylene oxide/ethylene oxide block copolymer (avreage MW of polypropylene oxide 1,700W2,000, ethylene oxide content 40W80wt%). Then, a vinyl chloride type monomer is suspension-polymerized in the presence of 0.01W0.5wt% of said suspension stabilizer.
