Golf balls having a portion or layer formed from a polymeric composite that preferably includes at least two polymers with distinct microstructures. In particular, the balls can include a polybutadiene having at least about 80 percent cis-isomer polybutadiene blended with a polybutadiene having at least about 50 percent trans-isomer polybutadiene. Methods of preparing such golf balls are also recited.

The invention relates to the preparation of a silica reinforced rubber composition where alkoxysilane and/or sulfur cure reactions within the elastomer host are controlled by the use of a selected amino acid, or amino acid-containing protein based, activator. The invention also relates to such composite and to a tire having at least one component of such composite.

It has been unexpectedly discovered that cis-1,4-polybutadiene that is synthesized utilizing Zeigler-Natta catalyst systems has superior characteristics for utilization in solid golf ball cores if the polymerization is terminated utilizing a carboxylic acid of the structural formula RCOOH, wherein R represents an alkyl group containing from 1 to about 30 carbon atoms.
