Title (EN) VINYL HALIDE POLYMERS MODIFIED WITH OLEFINIC NITRILE POLYMERS
(FR) POLYMERES D'HALOGENURE VINYLIQUE MODIFIES AU MOYEN DE POLYMERES AU NITRILE OLEFINIQUE
Abstract:
(EN) Vinyl halide polymer compositions exhibiting reduced gas permeability are described which comprise a mixture of (A) at least one vinyl halide polymer; and (B) from about 1 to about 40 parts by weight per 100 parts of vinyl halide polymer (A) of at least one olefinic nitrile polymer. The vinyl halide polymers preferably are vinyl chloride homopolymers and copolymers, and the olefinic nitrile polymers are copolymers of an olefinically unsaturated nitrile such as acrylonitrile and one or more monomers from the group of conjugated dienes, monoolefins, olefinically unsaturated carboxylic acid esters, and vinyl aromatic compounds. The olefinic nitrile polymer can be chosen or manufactured to have a refractive index which is similar to the refractive index of the vinyl halide polymer thereby resulting in a more transparent composition.
(FR) Sont décrites des compositions polymères d'halogénure vinylique présentant une perméabilité réduite au gaz, qui comprennent un mélange de: (A) au moins un polymère d'halogénure vinylique; et (B) environ 1 à environ 40 parties en poids pour 100 parties de polymère d'halogénure vinylique (A) d'au moins un polymère au nitrile oléfinique. Les polymères d'halogénure vinylique sont préférablement des homopolymères et des copolymères au chlorure de vinyle d'un nitrile non saturé à l'oléfine comme de l'acrylonitrile et un ou plusieurs monomères provenant du groupe de diènes conjugués, de monooléfines, d'esters d'acide carboxylique non saturés à l'oléfine, et de composés aromatiques de vinyle. On peut choisir ou produire le polymère au nitrile oléfinique afin qu'il ait un indice de réfraction similaire à l'indice de réfraction du polymère d'halogénure vinylique, ce qui donne alors une composition plus transparente.
