WATER-RESISTANT POLYVINYL ALCOHOL-BASED COPOLYMER AND SYNTHETIC RESIN EMULSION OBTAINED WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a vinyl alcohol-based polymer having a high water-resistant performance and excellent aqueous solution viscosity stability.;SOLUTION: This vinyl alcohol-based polymer having saturated cyclic alkyl groups on side chains and exhibiting a high water-resistant performance and excellent aqueous solution viscous stability is obtained by copolymerizing a vinyl ether having a saturated cyclic alkyl group with vinyl acetate and then saponifying the obtained copolymer.;COPYRIGHT: (C)2003,JPO
