| titleOfInvention | Suspension stabilizer for polymerization of vinyl compound |
| abstract | PURPOSE: To provide a suspension stabilizer for the polymerization of vinyl compounds, comprising a lactone-ring-containing modified polyvinyl alcohol having a specific degree of saponification, and useful for the production of a polymer free of fish-eye. n CONSTITUTION: A modified polyvinyl alcohol containing 0.1W15 mol%, pref. 3W10 mol% of lactone ring and having a degree of saponification of 60W95%, pref. 75W90%, is used as a suspension stabilizer for the polymerization of a vinyl compound such as vinyl chloride. The suspension stabilizer is prepared by (1) copolymerizing vinyl acetate with an ethylenic unsaturated carboxylic acid alkyl ester, and (2) saponyfying the copolymer in absolute alcohol in the pesence of 0.001W 0.06 mole equivalent, based on the vinyl acetate, of an alkali catalyst. The vinyl chloride polymer prepared by using the above suspension stabilizer has high plasticizer absorption, and gives a film free from fish-eye. n COPYRIGHT: (C)1979,JPO&Japio |
