Title (EN) POLYMER PROCESSING ADDITIVE, COMPOSITIONS, AND METHODS
(FR) ADDITIF DE TRAITEMENT DE POLYMÈRES, COMPOSITIONS ET PROCÉDÉS
Abstract: front page image
(EN)A poly(oxyalkylene) polymer and a metal salt of a carboxylic acid, sulfonic acid, or alkylsulfate, in combination are useful as a polymer processing additive synergist. Polymer processing additive compositions, homogeneously catalyzed olefin compositions, and other extrudable polymer compositions including a poly(oxyalkylene) polymer and a metal salt of a carboxylic acid, sulfonic acid, or alkylsulfate are disclosed. Methods of reducing melt defects during the extrusion of a thermoplastic polymer, which may be a homogeneously catalyzed polyolefin, are also disclosed.
(FR)Une combinaison d'un polymère poly(oxyalkylène) et d'un sel métallique d'un acide carboxylique, d'un acide sulfonique ou d'un alkylsulfate est utile comme additif synergiste de traitement de polymères. L'invention concerne des compositions d'additifs de traitement de polymères, des compositions d'oléfines catalysées de manière homogène, et autres compositions de polymères pouvant être extrudées, notamment un polymère poly(oxyalkylène) et un sel métallique d'un acide carboxylique, d'un acide sulfonique ou d'un alkylsulfate. L'invention concerne également des procédés de réduction des défauts de fusion pendant l'extrusion d'un polymère thermoplastique, qui peut être une polyoléfine catalysée de manière homogène.
