Abstract
A heterogeneous rubbery polymer is provided that includes a polymer chain derived from a vinyl aromatic monomer and a conjugated diolefin monomer, wherein from greater than 20 weight percent to about 40 weight percent of units in the rubbery polymer are derived from the vinyl aromatic monomer and from about 60 weight percent to about 80 weight percent of units in the rubbery polymer are derived from the conjugated diolefin monomer. The polymer chain is further characterized by having greater than zero and less than about 30 weight percent of the vinyl aromatic units in sequences containing 1 vinyl aromatic unit, from about 5 weight percent to about 20 weight percent of the vinyl aromatic units in sequences containing 5 to 8 vinyl aromatic units, and greater than zero and less than about 5 weight percent of the vinyl aromatic units in sequences containing 9 or more vinyl aromatic units.
