FREMGANGSMAATE TIL FREMSTILLING AV ET SMELTEKLEBESTOFF PAA BASIS AV POLYVINYLALKOHOL |
摘要 |
A resin-like product having a degree of hydrolysis of 50 to 70 mole percent is obtained by selective alcoholysis of a vinyl ester copolymer, if desired in the form of a mixture with a vinyl ester homopolymer. The starting material employed is preferably a vinyl acetate/crotonic acid copolymer. The resin is suitable for use as a hot-melt adhesive which forms coherent films capable of being activated by water or water vapor. |
