Oxyalkylene group-containing polyvinyl alcohol resin composition and process for the production of shaped articles from said composition

摘要

The invention provides an oxyalkylene group-containing PVA resin composition with an alkali metal acetate content of 0.001 DIFFERENCE 1 weight % and an oxyalkylene group-containing PVA resin composition with an alkali metal acetate content of 0.001 DIFFERENCE 1 weight %, which further contains 0.1 DIFFERENCE 10 moles of an acid with a pKa value of not more than 5.0 per mole of the alkali metal acetate, optionally together with 0.01 DIFFERENCE 5 weight of a phenol compound which melts at 50 DEG DIFFERENCE 250 DEG C., a thioether or a phosphite based on the polyvinyl alcohol and/or 0.01 DIFFERENCE 3 weight % of a fatty acid compound based on the polyvinyl alcohol.
