Title
(EN) POLYPHENYLENE SULFIDE ALLOY COMPOSITION
(FR) COMPOSITION D'ALLIAGE AU SULFURE DE POLYPHENYLENE
Abstract
(EN) The present invention relates to polymer compositions containing polyphenylene sulfide, a polymeric grafting agent and an ethylene copolymer. The polymeric grafting agent is a copolymer of at least about 50 % by weight ethylene, about 0.5 % to about 15 % by weight of a first reactive moiety selected from the group consisting of: (i) an unsaturated epoxide of 4-11 carbon atoms, (ii) an unsaturated isocyanate of 2-11 carbon atoms, (iii) an alkoxy or alkyl silane wherein the alkyl group is from 1-12 carbon atoms, and (iv) an oxazoline; and about 0 to about 49% by weight of a second moiety selected from at least one of an alkyl acrylate, alkyl methacrylate, vinyl ether, carbon monoxide, and sulfur dioxide, where the alkyl and ether groups are of 1-12 carbon atoms. The ethylene copolymer comprises about 1 % to about 20 % by weight of an ethylene copolymer which comprises at least about 50 % by weight ethylene, about 1 % to about 35 % by weight of an acid-containing unsaturated mono-carboxylic acid, and about 0 to about 49 % by weight of a moiety selected from at least one of alkyl acrylate, alkyl methacrylate, vinyl ether, carbon monoxide, and sulfur dioxide, and further wherein the acid groups are neutralized from 0-100% by a metal ion. The molar ratio of polymeric grafting agent to ethylene copolymer preferably ranges from about 1.0 to about 5.5.
(FR) La présente invention concerne des compositions polymères contenant du sulfure de polyphénylène, un agent de greffage polymère et un copolymère éthylénique. L'agent de greffage polymère est un copolymère composé: d'au moins 50 % en poids d'éthylène; d'environ 0,5 % à environ 15 % en poids d'un premier groupe fonctionnel réactif choisi parmi le groupe comprenant (i) un époxyde insaturé de 4 à 11 atomes de carbone, (ii) un isocyanate insaturé de 2 à 11 atomes de carbone, (iii) un alkoxy ou alkyl silane dans lequel le groupe alkyle possède 1 à 12 atomes de carbone, et (iv) une oxazoline; et d'environ 0 à environ 49 % en poids d'un second groupe fonctionnel choisi parmi au moins un alkyl acrylate, alkyl méthacrylate, vinyl éther, monoxyde de carbone, et dioxyde de soufre, les groupes alkyle et éther comportant 1 à 12 atomes de carbone. Le copolymère éthylénique comprend d'environ 1 % à environ 20 % en poids d'un copolymère éthylénique comprenant au moins 50 % en poids d'éthylène, d'environ 1 % à environ 35 % en poids d'un acide monocarboxylique insaturé à base d'acide, et d'environ 0 à environ 49 % en poids d'un groupe fonctionnel choisi parmi au moins un alkyl acrylate, alkyl méthacrylate, vinyl éther, monoxyde de carbone, et dioxyde de soufre, et les groupes acides étant neutralisés de 0 à 100 % par un ion métallique. La fraction molaire de l'agent de greffage polymère par rapport au copolymère éthylénique vaut de préférence entre 1,0 et 5,5.
