    摘要: A composition includes a baleable polymer resulting from the polymerization of at least one conjugated diene in the presence of an anionic initiator. The baleable polymer has carboxylate termination resulting from the addition of carbon dioxide to terminate the polymerization reaction. The polymer has Mooney ML1+4 viscosity of >35 and a solution viscosity of X, where X is >75 cP. The addition of an lonolizer to a composition that includes the polymer reduces the solution viscosity of the polymer from X to Y where Y meets the following formula: 0.4X≦Y≧0.58X. The baleable polymer is blended with impact-modified plastics resulting in improved izod values and optical qualities. Processes for making and utilizing the polymer composition, and ionolizer are also described.
