Title
(EN) LOW COMPRESSION, RESILIENT GOLF BALLS INCLUDING AN ORGANOSULFUR CATALYST AND METHOD FOR MAKING SAME
(FR) BALLES DE GOLF ELASTIQUES, A FAIBLE COMPRESSION, COMPRENANT UN CATALYSEUR ORGANOSULFURE ET PROCEDE DE PRODUCTION ASSOCIE
Abstract
(EN)
A low compression, resilient golf ball having a center and a cover, made from a polybutadiene reaction product having polybutadiene, a cis-to-trans catalyst including an organosulfur component, and a free radical source. The reaction product has a first dynamic stiffness measured at -50 °C that is less than about 130 percent of a second dynamic stiffness neasured at 0 °C. A multi-layer golf ball having a center, at least one intermediate layer disposed concentrically about the center, and a cover. At least a portion of at least one of the center, intermediate layer, or both, are made from a reaction product including polybutadiene having a cis-to-trans catalyst that includes at least one organosulfur component and a free radical source. The reaction product has a first dynamic stiffness measured at -50 °C that is less than about 130 percent of a second dynamic stiffness measured at 0 °C. Addition of various combinations of polybutadiene, cis-to-trans catalyst including at least one organosulfur component, free radical source, filler, and crosslinker, produce golf balls and golf ball components that are resilient (fast) and have low compression (soft).
(FR)
La présente invention concerne une balle de golf élastique, à faible compression, comportant un noyau et une enveloppe, produite à partir d'un produit de réaction de polybutadiène. Cette réaction met en oeuvre du polybutadiène, un catalyseur de conversion de cis en trans contenant un composant organosulfure, et une source de radicaux libres. Le produit de réaction présente typiquement une rigidité dynamique qui, mesurée à 50 °C, est inférieure d'environ 130 pour cent à une seconde rigidité dynamique mesurée à 0 °C. L'invention concerne aussi une balle de golf à couches multiples présentant un noyau, au moins une couche intermédiaire disposée de manière concentrique autour du noyau, et une enveloppe. Au moins une portion d'un noyau, d'une couche intermédiaire ou des deux est fabriquée à partir d'un produit de réaction comprenant du polybutadiène avec un catalyseur de conversion de cis en trans, à base d'au moins un composant organosulfure, et une source de radicaux libres. L'addition de nombreuses combinaisons de polybutadiène, de catalyseur de conversion cis en trans comprenant au moins un composant aromatique, une source de radicaux libres, une charge, et un agent de réticulation, permet de produire des balles de golf et des composants de balle de golf qui sont élastiques (rapides) et possèdent une faible compression (douces au toucher).
