(FR) ENVELOPPES DE BALLES DE GOLF
Abstract
(EN)
The invention is directed to a golf ball comprising a core and a cover, wherein the cover comprises a blend of at least one olefinic ionomer and a terpolymer, said terpolymer comprising a first monomeric component comprising an olefinic monomer having from about 2 to about 8 carbon atoms, a second monomeric component selected from unsaturated acrylate class ester having from about 2 to about 18 carbon atoms and, a third monomeric component comprising at least one monomer selected from the group consisting of carbon monoxide, anhydride monomers and monomers having a sructure according to formula (I) wherein R1 is a linear chain or branched chain alkyl group of from about 1 to about 18 carbon atoms and R2 is selected from the group consisting of linear chain or branched chain alkyl, substituted or unsubstituted carbocyclic and substituted aryl groups containing an epoxy, i.e., glycidyl moiety.
(FR)
L'invention porte sur une balle de golf présentant un noyau ainsi qu'une enveloppe, laquelle comprend un mélange d'au moins un ionomère oléfinique et d'un terpolymère; ce terpolymère comporte un premier constituant monomère composé d'un monomère oléfinique possédant d'environ 2 à environ 8 atomes de carbone, un second constituant monomère choisi dans une classe d'esters insaturés d'acrylate possédant d'environ 2 à environ 18 atomes de carbone, ainsi qu'un troisième constituant monomère comprenant au moins un monomère choisi dans le groupe constitué par un monoxyde de carbone, des monomères d'anhydride, et des monomères présentant une structure correspondant à la formule (I) dans laquelle R1 représente un groupe alkyle à chaîne droite ou ramifiée, possédant d'environ 1 à environ 18 atomes de carbone, et R2 est choisi dans le groupe constitué par alkyle à chaîne droite ou ramifiée, des groupes carbocycliques substitués ou non et aryles substitués, et qui contiennent un époxy, c'est-à-dire une fraction glycidyle.
