Vinylidene chloride polymer compositions and irradiated articles prepared therefrom

摘要

A composition comprising a mixture of (1) a vinylidene chloride polymer formed from a monomer mixture wherein the major component is vinylidene chloride and the remainder is at least one ethylenically unsaturated monomer copolymerizable therewith and (2) an amount of an aliphatic ester compound sufficient to minimize color degradation (formation of color bodies) of the vinylidene chloride polymer during and after irradiation of the composition is used to prepare a heat-shrinkable multilayer film. The composition may also contain an amount of a color stable violet or blue dye sufficient to mask color bodies formed during and after irradiation of the composition.
