High performance segmented elastomer

摘要: It is highly desirable for tire treads to exhibit good traction characteristics such as wet skid resistance. However, it has traditionally been very difficult improve the of a without sacrificing rolling resistance and tread wear. The high performance segmented elastomers this invention offer unique combination utilization in making compositions. For instance, rubbery polymers can be made into which outstanding while maintaining durability. This more specifically reveals rubber polymer an excellent properties use comprised repeat units are derived essentially from at least one conjugated diene monomer, wherein first segment number average molecular weight within range about 25,000 350,000; (b) final 1,3-butadiene, isoprene, styrene, random order, 350,000.
