Poly(vinyl alcohol) composition comprising a polyol
First Claim
1. A composition comprising or produced from a polyol ester plasticizer and poly(vinyl alcohol) whereinthe poly(vinyl alcohol) comprises poly(vinyl alcohol-co-methyl methacrylate), poly(vinyl alcohol-co-methyl acrylate), or combinations thereof and has at least about 80% hydrolysis;
- the polyol ester plasticizer comprises an esterified polyol having one or more ester groups and at least one free hydroxyl group and is present in the composition in an amount sufficient to transesterify and increase the ester content of the poly(vinyl alcohol); and
the polyol ester is derived from one or more polyols and one or more C1-5 alkanoic acids and the C1-5 alkanoic acid optionally comprises a functional group including hydroxy, trialkylamino, ether, or combinations of two or more thereof.
