The present invention encompasses a golf ball having a diameter and being comprised of a core and a cover, wherein the core is further comprised of a fluid mass at the center of the ball, and a first, solid, non-wound mantle layer surrounding the fluid mass, wherein the first mantle layer comprises a copolymer or terpolymer of ethylene and an α,β-unsaturated carboxylic acid, the acid being neutralized at least 80% by a salt of an organic acid, a cation source, or a suitable base of the organic acid, and wherein the cover comprises polyurethane, polyurea, or a polyurea/polyurethane hybrid. Preferably, the rate of spin decay is at least 10% of an initial spin rate of the golf ball over the entire ball flight.

Multilayer golf ball

A method for manufacturing a conductive composition comprises blending a polymer precursor with a single wall carbon nanotube composition; and polymerizing the polymer precursor to form an organic polymer. The method may be advantageously used for manufacturing automotive components, computer components, and other components where electrical conductivity properties are desirable.

Electrically conductive compositions and method of manufacture thereof

The present invention is directed towards a multi-layer golf ball which comprises a core, a cover layer and at least one intermediate layer disposed between the core and cover, wherein the intermediate layer comprises a polyether-type polyurethane and optionally, a second thermoplastic component such as polyetherester block copolymer, polyesterester block copolymer, polyetheramide block copolymer, dynamically vulcanized thermoplastic elastomer, functionalized styrene-butadiene elastomer, thermoplastic polyurethane, thermoplastic polyesters, metallocene polymer or blends thereof and a density-modifying filler such as zinc oxide, titanium dioxide or blends thereof.

Multi-layered golf ball and composition

A method for making a multilayer golf ball including a solid center having a center hardness, a plurality of laminates cut into a plurality of shapes formed around the center to create an inner ball, and a cover formed around the inner ball, wherein the plurality of layers can include at least a first layer having a hardness greater than the center hardness and a second layer having a hardness greater than the first layer hardness, and optionally a third layer disposed between the first and the second layers having a hardness greater than the first layer hardness.

Method of making a golf ball with a multi-layer core

An improved, conductive, polymeric composition comprises a polymeric resin; an electrically conductive filler system comprising small carbon fibers and either carbon powder or fibrous non-conductive filler or a combination of both. The amount of the conductive filler system utilized is dependent upon the desired electrical conductivity (surface and volume conductivity or resistivity) while preferably preserving intrinsic properties of the polymeric resin such as impact, flex modulus, class A finish, and the like. The conductive articles made from these compositions can therefore be used for electromagnetic shielding, electrostatic dissipation or antistatic purposes in packaging, electronic components, housings for electronic components and automotive housings.

Conductive plastic compositions and method of manufacture thereof

Copolyetheresteramide based compositions which are stable with respect to the effects of heat, light and oxygen are disclosed. From about 0.05 to about 5% of 4-4'-bis-(α-α'-dimethylbenzyl)-diphenylamide either alone or in combination with 0.01 to 2% of cuprous iodide and potassium iodide such that the ratio of CuI to KI is between 0.1 and 1.9 is added to the copolyetheresteramide to form a stable composition.

Thermoplastic polymer cover for golf balls. The thermoplastic polymer material constituting the cover consists of a poly(ether-ester-amide) sequenced copolycondensate having special characteristics. Such a cover has good mechanical characteristics and confers on the golf balls so covered a satisfactory "feel" and "click".

Hydrolysis-resistant copolyether-esteramides according to this invention are terminated, at one chain end, by a hydrocarbon radical and at the other chain end by a hydroxyl group. The sequential linear aliphatic copolyether-esteramides according to the invention are obtained by a polycondensation reaction of linear aliphatic dicarboxylic polyamide oligomers having a molecular weight comprised between 300 and 15,000, with ω-ω'-dihydroxyl polyoxyalkylene sequences having a molecular weight comprised between 100 and 6000 in the presence of a linear aliphatic monocarboxylic polyamide oligomer having a carboxyl group at one end of the macromolecular chain and a hydrocarbon radical at the other end thereof.

Hydrolysis-resistant copolyether-esteramides

Sequenced aliphatic copolyetheresteramides of high mol. wt. are prepd. by polycondensing in the melt and at 150-300 deg.C. and atmos. pressure a linear aliphatic polyamide having terminal -NH2 gps. and a mol. wt. of 300-5000 with a polyoxyalkylene glycol having terminal -COOH or -COOR gps. and mol. wt. 200-3000, in the presence of 0.05-5% catalyst comprising phosphorus oxyacids or their ammonium salts. The prods. can be moulded or extruded to (semi)rigid articles. Their prepn. does not involve use of vacuum (cf. FR2273021). Reaction is also faster and residence time shorter, thus avoiding thermal degradation.

Copolyetheresteramides aliphatiques lineaires sequences stables a l'hydrolyse, termines a une extremite de la chaine par un radical hydrocarbone et a l'autre extremite par un groupe hydroxyle qui sont obtenus par reaction d'une sequence polyamide de type 6, 6-6, 6-10, Il ou 12 avec un polyoxyethyleneglycol, un polyoxypropyleneglycol ou un polyoxytetramethyleneglycol en presence d'un polyamide oligomere ayant une extremite de sa chaine terminee par un groupement COOH et l'autre extremite par un radical hydrocarbone.
