Abstract: The present invention is directed to a golf ball cover comprising a blend of copolymers wherein one or more of the copolymers is a low cost non-ionic copolymer and one or more of the copolymers is an ionic copolymer. Surprisingly, a golf ball cover comprising the non-ionic/ionic copolymer blend exhibits no loss in C.O.R., and has equal resistance to cutting and cracking when compared to top grade golf ball covers made with one of the conventional 100% ionic copolymer blends. In particular, the present golf ball cover comprises from about 95 to about 80 pphr of one or more ionic copolymers, and from about 5 to about 20 pphr of one or more non-ionic copolymers, the latter being selected from the group consisting of a copolymer or terpolymer of ethylene or propylene; acrylic acid or methacrylic acid; a lower alkyl acrylate, and blends thereof.

Three different diameters of dimples are used within the pattern.

Abstract: An improved golf ball comprising a hollow, spherical shell of a polymeric material; a unitary, noncellular core of a material which, at the time of introduction into the shell, is a liquid and a one-piece spherical cover over the center. The spherical shell, as opposed to the core, is primarily responsible for the high initial velocity obtained when the golf ball is struck by a golf club so as to allow the golf ball to be driven long distances both in the air and on the ground when it lands. In an alternate embodiment, the center and cover are of a one-piece, blow-molded construction.

Abstract: The present invention is directed to restricted or limited flight golf balls. Specifically, new elastomeric blends are provided for forming the cores of one piece or multi-layered balls having the desired reduced coefficient of restitution (C.O.R.) values necessary for restrictive flight performance (i.e. elastomeric blends having C.O.R. values when cured of about 0.560 to about 0.670, with C.O.R. values of about 0.560 to about 0.640 being preferred for the core composition of multi-layered restricted flight golf balls). This is accomplished utilizing the elastomeric blends of the invention without sacrificing the compression (hardness), weight and feel of the resulting cured product.

Abstract: An improved golf ball having a coefficient of restitution of at least 0.700 and comprising a hollow, spherical shell of a deformable polymeric material which is filled with either a liquid or a unitary, non-cellular core of a material which, at the time of introduction into the shell, is a liquid. The spherical shell may be solid or cellular. The core material may be added through a hole in the shell as a liquid, a gel or a melt. In the preferred embodiment, the spherical shell is formed from two half shells which are bonded to each other. The mating edges of the half shells may have surface configurations which maximize their contact area.

Abstract: The disclosure relates to golf balls and more particularly, to golf ball cover compositions. The disclosure is concerned primarily with composition and method for the enhancement of the color of a golf ball cover by the use of an optical brightener in conjunction with a pigmented golf ball cover composition. This invention is concerned with the enhancement of the color of white golf ball covers. When used in conjunction with a white pigmentation system, the optical brighteners in question enhance the color in the blue spectrum range in order to give the cover a whiter appearance.

Abstract: Disclosed is a golf ball having improved short iron and wood playability and improved puttability relative to conventional, ionomer covered balls. The golf balls comprise a novel cover which is far more durable than balata-covered balls yet closely approach or exceed their playability characteristics. The cover comprises a blend of a thermoplastic urethane having a Shore A hardness less than 95 and an ionomer having a Shore D hardness greater than 55. The relative amounts of the urethane and ionomer are set so that the cover has a Shore C hardness within the range of 70 to 85, most preferably 72 to 76.
