Abstract
Official abstract text for this publication.
An object of the present invention is to provide a golf ball with an improved controllability by enhancing a dry spin rate and wet spin rate in a so-called distance type golf ball. The present invention provides a golf ball comprising a constituting member that is formed from a polyurethane composition containing, as a resin component, a polyurethane elastomer using 1,4-bis(isocyanatomethyl)cyclohexane as a polyisocyanate component, wherein the polyurethane composition has a shear loss modulus G″ of more than 5.03×10 6 Pa and 1.17×10 8 Pa or less when measured in a shear mode using a dynamic viscoelasticity measuring apparatus at the conditions of the temperature of 0° C., and the oscillation frequency of 10 Hz.
First claim
Opening claim text (preview).
What is claimed is: 1. A golf ball comprising a core and a cover covering the core, wherein the cover is formed from a polyurethane composition containing, as a resin component, a polyurethane elastomer formed from 1,4-bis(isocyanatomethyl)cyclohexane as the only polyisocyanate component, wherein the resin component of the polyurethane composition contains the polyurethane elastomer in a content of 50 mass % or more, and wherein the polyurethane composition has a rebound resili…
