1. A golf ball, comprising:
- a molded core comprising a high cis-polybutadiene having a Mooney viscosity of from about 20 to about 70 and an Instron compression of greater than 0.0880;
a mantle comprising a highly neutralized ionomer and a fatty acid, the mantle having a Shore D hardness of from about 30 to about 85; and
and a cover composed of a high flexural modulus ionomer material;
wherein the golf ball has a diameter of at least 1.68 inches.

Abstract
A golf ball comprises a molded core, one or more ionomer mantles, and a thermoset polyurethane cover. The core is a high cis-polybutadiene crosslinked with zinc diacrylate and may also comprise a halogenated thiophenol and metal thiosulfate. One or more of the ionomer mantles comprises an ionomer neutralized to 80% or greater.
