Title (EN) MULTI-LAYER GOLF BALL
(FR) BALLE DE GOLF MULTICOUCHE
Abstract:
(EN) A golf ball has an ionomer resin core center, a cured rubber layer made from (a) an at least 70% cis-1,4 polybutadiene with Mooney viscosity (ML1+4(100C)) ≥40, (b) an unsaturated carboxylic acid or metal salt, and (c) a free radical initiator; and a cover including a thermoplastic material. The core center has a diameter of 21-29 mm and a 10-130 kg compression deformation (C) ≥4 mm. The core layer is ≥5 mm thick with a specific gravity ≥0.1 g/cm3 greater than that of the core center. The cover may have a flexural modulus ≥15,000 psi or ≤35,000 psi. Also disclosed is a golf ball with an ionomer core center having C1 ≥ 3.5 mm, a cured rubber core layer ≥5 mm thick with C2 ≥3 mm, and a cover with C3 ≥2.8 mm, with C2/C1 and C3/C2 about 0.8-1.
(FR) L'invention concerne une balle de golf présentant un centre de noyau en résine ionomère, une couche de caoutchouc durcie composée (a) d'au moins 70 % de cis-1,4 polybutadiène présentant une viscosité de Mooney (ML1+4(100C)) ≥ 40, (b) d'un acide carboxylique insaturé ou d'un sel métallique, et (c) d'un initiateur de radicaux libres ; et d'une couverture comprenant un matériau thermoplastique. Le centre du noyau présente un diamètre de 21-29 mm et une déformation à une compression de 10-130 kg (C) ≥ 4 mm. La couche centrale présente une épaisseur ≥ 5 mm et un poids spécifique ≥ 0,1 g/cm3 supérieurs à ceux du centre du noyau. La couverture peut présenter un module de flexion ≥ 15 000 psi ou ≤ 35 000 psi. L'invention concerne également une balle de golf pourvue d'un centre de noyau ionomère ou présentant C1 ≥ 3,5 mm, une couche centrale de caoutchouc durci ≥ 5 mm d'épaisseur avec C2 ≥ 3 mm, et une couverture avec C3 ≥ 2,8 mm, 1 et C3/C2 atteignant environ 0,8-1.
