Functional modification of poly(vinyl alcohol) by copolymerization: 1. Modification with car☐ylic monomers

Publikováno v: Polymer. 38:2933-2945

For the purpose of obtaining modified poly(vinyl alcohol-co-vinyl acetate), or partially hydrolysed poly(vinyl alcohol) (PVAL), containing sodium car☐ylate groups, -COONa, in polymer chains, ten car☐ylic monomers have been investigated for copoly
