Abstract: A composition suitable for forming a sidewall for a tire includes a rubber composition which includes at least one rubber, an ethylene/propylene/diene terpolymer, and a polyalkylene copolymer. The rubber may include one or more natural or synthetic rubbers, such as butadiene rubbers and isoprene rubbers. The ethylene/propylene/diene terpolymer preferably has an ethylene content of at least 60%. The polyalkylene copolymer may be a copolymer of a polyalkylene and an null-olefin, which is formed in a polymerization reaction involving a single site catalyst. The polyalkylene copolymer preferably has a high degree of crystallinity, being preferably at least about 90% by weight ethylene, with a melting point in the range of 80null C.-120null C. The presence of such a copolymer in the rubber composition markedly increases the resistance to crack growth and formation of cracks in the tire sidewall.

Abstract: A polymer composition comprises a low-molecular-weight (LMW) ethylene polymer component and a high-molecular-weight (HMW) ethylene polymer component. Preferably, the LMW polyethylene component and the HMW polyethylene component co-crystallize in the composition such that it exhibits a single or substantially single peak in a lamella thickness distribution (nullLTDnull) curve. The ethylene polymer for the LMW and the HMW polyethylene components can be either homopolyethylene or ethylene copolymer. Preferably, both components are an ethylene copolymer of the same or different composition (i.e., with the same or different comonomers). A method of making a pipe that includes selecting a polymer composition having a substantially single peak in the LTD curve is described.
