ABSTRACT:
A crosslinkable low viscosity short arm star polymer blend made by anionically polymerizing a conjugated diene and, optionally, a vinyl aromatic hydrocarbon to form living polymer arms and coupling said arms with a coupling agent for star polymers and blending said star polymer with a compatible organic liquid such that the amount of organic liquid in the blend ranges from 5 to 50 percent by weight. A preferred embodiment is an epoxidized version which is selectively epoxidized at the exterior sections of the polymer to enhance the crosslinkability of the polymer.
