Abstract
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.
Claims22
A golf ball which is comprised of a solid core and a resin cover, wherein the solid core is comprised of cis-1,4-polybutadiene rubber which is made by polymerizing 1,3-butadiene in the presence of a Ziegler-Natta catalyst wherein the polymerization is short-stopped with a carboxylic acid of the structural formula RCOOH wherein R represents an alkyl group containing from 1 to about 30 carbon atoms.
A golf ball which is comprised of a solid core and a resin cover, wherein the solid core is comprised of cis-1,4-polybutadiene rubber which is made by polymerizing 1,3-butadiene in the presence of a nickel catalyst system wherein the polymerization is short-stopped with a carboxylic acid of the structural formula RCOOH wherein R represents an alkyl group containing from 1 to about 30 carbon atoms.
