Abstract
This polymer comprises (a) about 15 to 5 weight percent of units from at least one nitrile monomer of the formula ##STR1## where R is hydrogen or methyl; (b) about 75 to 90 weight percent of units from vinylidene chloride, and (c) about 10 to 5 weight percent of units from at least one acrylate monomer of the formula ##STR2## where R' is hydrogen or alkyl of 1 to 4 carbon atoms and R" is alkyl of 1 to 20 carbon atoms.
