摘要:
A golf ball incorporates nanofiller material in its core, cover, or intermediate layers. Also, a method includes a step of blending into a composition for a golf ball nanocomposite material, nanofiller material or both. The nanocomposite and/or nanofiller materials impart favorable properties to materials used for golf balls, and they provide for greater versatility in usage than materials previously used. Particular compositions incorporating nanocomposite material also are described as suited for use in golf ball compositions.

Embodiments of the disclosed polymer composition comprise a first unsaturated polymer or polymer precursor, and an effective amount of a peptizer. The peptizer typically comprises a heteroaryl or a heterocyclic compound, other than morpholine as disclosed in assignee's prior applications. Disclosed polymer compositions are useful for making sports equipment, such as at least one layer of a golf ball, often a core. Because the compositions are useful for making golf balls, materials commonly known for making such golf balls can be used in combination with the polymer composition. A method for forming a golf ball also is disclosed. The method comprises providing disclosed compositions and then forming at least one component of a golf using the composition.
摘要:
The present invention concerns polymer compositions to which a monomeric aliphatic, alicyclic, and/or aromatic amide, or amides, is added to advantageously modify the properties of such compositions for making sports equipment, such as golf balls. The amide is used in an amount effective to obtain desired composition properties, such as improved rheological properties, while maintaining or at least substantially maintaining properties of products made using the composition, such as the coefficient of restitution. The aliphatic or aromatic monomeric amide may be a primary amide, a secondary amide, a tertiary amide, a bis amide, and combinations thereof, and may have from about 5 to about 100 carbon atoms, more typically from about 10 to about 25 carbon atoms. Moreover, the amide may be saturated or may include one or more sites of unsaturation, such as at least one, and possibly plural double bonds that are substantially all trans, substantially all cis, or a mixture of cis and trans double bonds. One embodiment of a disclosed composition useful for making a golf ball comprises at least one polymer suitable for such use, and an amount of the amide effective to desirably modify the polymer properties. The composition may further include from about 1 to about 99 weight percent of at least one additional thermoplastic or thermoset polymeric material. The composition can be used to make any golf ball component, such as a golf ball core, at least one layer other than the core including the cover, or can be used to make more than one component of the golf ball, such as the core, an intermediate layer, and/or a golf ball cover. A method for forming a golf ball also is disclosed comprising providing an embodiment of the disclosed composition and forming at least one component of a golf ball comprising the composition.
摘要:
A golf ball, and method for making it, are disclosed wherein the golf ball includes a core including a center point having a first hardness value and/or first specific gravity value and an outer surface having a second hardness value and/or second specific gravity value. The first and second hardness values and the first and second specific gravity values are different from each other.

Provided is a fast handover method using candidate care-of addresses (CoAs). The method includes obtaining Internet protocol (IP) address information of access routers located adjacent to a previous access router (PAR) to which a mobile node is connected; setting more than one candidate CoAs based on the IP address information; and selecting from the more than one candidate CoAs a CoA of a sub-net to which the mobile node is to move and performing a handover based on the selected CoA. Therefore, a delay and a packet loss caused by the setting of a new NCoAs can be prevented.
