摘要 |
Vinyl esters are polymerized in the presence as polymerization medium of ethylene carbonate. The vinyl ester may be vinyl acetate and the polymer produced may be saponified to give a stable aqueous solution of polyvinyl alcohol. Azo-bis-isobutyronitrile may be used as polymerization catalyst. |
