摘要： Rubbery high trans-high vinyl diblock copolymers, blends of rubbery high trans copolymers and rubbery high vinyl polymers, and mixtures (alloys or blends) of said diblock copolymers, high trans copolymers and high vinyl polymers are useful in producing tire treads exhibiting good processibility, good rolling resistance, skid resistance and abrasion resistance. The high trans block or copolymer comprises a copolymer of butadiene-1,3 and styrene and/or isoprene and the high vinyl block or polymer comprises polybutadiene or copolymers of butadiene and styrene and/or isoprene. These di-block copolymers, copolymers and polymers are made by solution polymerization. The diblock copolymer may be made by copolymerizing butadiene and styrene and/or isoprene using a Ba, Ca or Sr alcoholate, R.sub.2 Mg and R.sub.3 Al to from about 60 to 95% conversion to a high trans block and then adding (optionally more Bd with or without Sty and/or isoprene) a strong Lewis base and a Na, K or Rb alkoxide and continuing the polymerization to completion to obtain the high vinyl block of the di-block copolymer.

摘要： A laminated product such as a tire is cast from chemically extending liquids which form a laminated solid in a mold. The mold cavity is closed in preparation for use except for casting fluid inlet ports and exhaust vents. The mold cavity defines the shape of the product to be cast. Two or more chemically extendable liquids are injected into the mold without mixing through the inlet ports. Each liquid is injected through a different port. After injection, the liquids are arranged in alternate circumferential segments within the annular space. At least one of the inner and outer surfaces which define the mold cavity is then rotated about the common axis to impart a spiral configuration to each of the injcted liquids. The liquids are then allowed to chemically extend to solids and form a laminated product such as a tire. The products, when they comprise alternate layers of high and low elastic modulus materials, have better resistance to flex cracking than non-layered materials of similar composition having similar average stiffness.
