Title
(EN) GOLF BALL COMPOSITIONS BASED ON ANIONIC POLYMERS
(FR) COMPOSITIONS POUR BALLES DE GOLF A BASE DE POLYMERES ANIONIQUES
Abstract
(EN)
The present invention provides golf balls having a cover, a core, and optionally one or more intermediate layers between the cover and the core, wherein at least one of the cover, the core and, if present, the intermediate layer or layers, includes an anionic polymer. The anionic polymer has at least one of a neutralizable hydroxyl or dealkylable ether group, at least a portion of which are neutralized or dealkylated by a metal ion to provide anionic moieties. The anionic polymer compositions of the present invention can be used to provide improved characteristics to golf balls made therefrom.
(FR)
La présente invention concerne des balles de golf comprenant une enveloppe, un noyau et facultativement une ou plusieurs couches intermédiaires situées entre l'enveloppe et le noyau, au moins un de ces constituants à savoir l'enveloppe, le noyau et si elles existent les couches intermédiaires, comprenant un polymère anionique. Le polymère anionique comprend au moins un groupe hydroxyle neutralisable ou un groupe éther désalkylable, dont au moins une partie est neutralisée ou désalkylée par un ion métallique pour produire des fractions anioniques. Les compositions polymères anioniques selon la présente invention peuvent être utilisées pour conférer des caractéristiques améliorées aux balles de golf produites à partir de ces dernières.
