Abstract
Official abstract text for this publication.
An object of the present invention is to provide a golf ball polyurethane composition excellent in resilience. Another object of the present invention is to provide a golf ball excellent in a shot feeling and resilience. The present invention provides a golf ball polyurethane composition comprising, as a resin component, a polyurethane elastomer including a polyisocyanate with at least two alicyclic hydrocarbon structures having 3 or more carbon atoms as a constituting component, and having a storage modulus E′ (Pa) and a loss modulus E″ (Pa) satisfying a following expression; log( E′/E″ 2 )≧−6.08 when measured in a tensile mode using a dynamic viscoelasticity measuring apparatus.
First claim
Opening claim text (preview).
What is claimed is: 1. A golf ball comprising a core composed of at least one layer and a cover covering the core, wherein at least one layer of the core is formed from a golf ball polyurethane composition comprising, as a resin component, a polyurethane elastomer formed from a polyisocyanate component of 4,4′-dicyclohexylmethane diisocyanate, a polyol component of polytetramethylene ether glycol having a number average molecular weight ranging from 2,000 to 3,000, and a chain ext…
