The invention is directed to an oil extended rubber and composition comprising:
a solution polymerized elastomer derived from isoprene and optionally at least
member of the group consisting of conjugated dienes and vinyl aromatic monomers;
and from about 5 to about 70 parts by weight, per 100 parts by weight of elastomer
(phr), of a process oil having a glass transition temperature of from about -80
C. to about -40 C. and a polycyclic aromatic content of less than 3 percent
by weight as determined by the IP346 method.
