    Abstract: Multi-piece golf balls having a core made of a polybutadiene rubber blend are provided. The golf ball contains a multi-layered core. The inner core is formed from a blend containing a non-metallocene catalyzed polybutadiene rubber and metallocene-catalyzed polybutadiene rubber. The surrounding outer core layer is made of a non-metallocene-catalyzed polybutadiene rubber. Catalysts such as neodymium, nickel, and cobalt based catalysts may be used to make the non-metallocene catalyzed rubber. Catalysts such as ferrocene, cobaltocene, nickelocene, titanocene dichloride, zirconocene dichloride, and samraocene based catalysts may be used to make the metallocene-catalyzed rubber. The multi-layered core is surrounded by a cover having at least one layer. The resulting ball has high resiliency and a soft compression feel.

    Abstract: A golf ball comprising an inner core formed from a substantially homogenous composition such that the geometric center hardness is 56-80 Shore C and the outer surface hardness is 50-75 Shore C. An outer core layer has an outer surface having hardness of 85-98 Shore C and an inner surface hardness of 68-78 Shore C and being formed from a second homogenous rubber composition. A cover layer is disposed about the outer core layer. The hardness of the second outer surface is greater than the hardness of the inner surface to define a positive hardness gradient of +7 to +30 Shore C, and the hardness of the first outer surface is lower than the hardness of the geometric center to define a negative hardness gradient of −1 to −15 Shore C.
