Abstract
To provide improved polymers having a more even distribution of crosslink points, thereby improving the crosslinking density and crosslink distribution of the cured polymer.SOLUTION: Embodiments of the present disclosure are directed to polymers, wherein the polymers include a conjugated diene and from about 0.02 wt.% to about 2.0 wt.% of vinylbenzocyclobutane, based on a total weight of the polymer. The polymer is a crosslinkable statistical copolymer of conjugated diene and vinylbenzocyclobutane monomer units.SELECTED DRAWING: None
