Title (EN) VINYLIDENE CHLORIDE POLYMER COMPOSITIONS AND IRRADIATED ARTICLES PREPARED THEREFROM
(FR) COMPOSITIONS DE POLYMERE DE CHLORURE DE VINYLIDENE ET ARTICLES IRRADIES PREPARES A PARTIR DESDITES COMPOSITIONS
Abstract:
(EN) 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.
(FR) Composition comprenant un mélange (1) d'un polymère de chlorure de vinylidène obtenu à partir d'un mélange de monomères, dans lequel le constituant principal est chlorure de vinylidène et le reste est au moins un monomère éthylèniquement insaturé copolymérisable avec ledit polymère et (2) une quantité d'un composé d'ester aliphatique suffisante pour diminuer au maximum la dégradation de la couleur (formation de masses colorées) du polymère de chlorure de vinylidène pendant et après l'irradiation de la composition, qu'on utilise pour préparer un film thermorétractable à couches multiples. Cette composition peut également contenir une quantité d'un colorant stable violet ou bleu, afin de masquer les masses colorées générées pendant et après l'irradiation de ladite composition.
