Abstract
A golf ball having a core and at least one layer disposed about the core is disclosed. The core may further include a center and an outer core layer disposed about the center. The layer is formed from a composition having a prepolymer and a curative, the prepolymer being formed from an isocyanate and a blend of two or more telechelic polyahls, wherein a first telechelic polyahl has a first functionality of 3 or greater, which is greater than a second functionality of a second telechelic polyahl in the blend. The layer displays an enhanced shear resistance.

A golf ball, comprising:
- a core;
- and
- at least one layer disposed about the core, the layer comprising a composition formed from a prepolymer and a curative, the prepolymer being formed from an isocyanate and a blend of two or more telechelic polyahls, wherein a first telechelic polyahl has a first functionality of 3 or greater and a first polydispersity, a second telechelic polyahl has a second functionality of 1.6 to 2.3 and a second polydispersity, wherein at least one of the first and second telechelic polyahls is a telechelic polyhydrocarbon polyahl or a hydrogenated telechelic polyhydrocarbon polyahl, and wherein the layer displays an enhanced shear resistance.
