  • Patent number: 6329459
    Abstract: There are disclosed a block copolymer of at least one elastomeric block and at least one syndiotactic polystyrene block which comprises 100 parts by weight of a polymer component comprising 1 to 80% by weight of syndiotactic polystyrene (sPS) block(s) and 99 to 20% by weight of rubbery elastomeric block(s) and at least 30 parts by weight of an extender. These extended block copolymer compositions display the characteristics of thermoplastic elastomers and are useful for high temperature applications possessing unique softness.

  • Patent number: 6017985
    Abstract: Novel silicon-containing derivatives of crystalline, high-trans-1,4 polybutadiene in which organosilicon-containing groups are bonded to the 1,2-vinyl carbon atoms along the main chain of the butadiene polymers through the carbon-silicon linkages. These derivatives of butadiene polymers are produced by the addition reaction of an organosilicon-compound having one hydrogen atom directly bonded to the silicon atom in the molecule to the double bonds in the 1,2-vinyl group butadiene polymers. These derivatives having good compatibility with siliceous fillers and when blended with filled diene rubbers are cured to elastomer compositions having excellent properties suitable for the production of tires.

  • Patent number: 5596053
    Abstract: Diene polymers having a high content of trans-1,4 addition and two distinct melting points in the ranges of 30.degree. C. to 50.degree. C. and 70.degree. C. to 130.degree. C. are prepared by polymerizing a 1,3-diene monomer in a hydrocarbon solvent in the presence of a catalyst composition comprising (a) a carboxylated nickel oxy borate compound; (b) an orKanoaluminum compound; (c) a triaryloxy phosphorus compound and (d) a carboxylic acid preferably a fluorinated carboxylic acid. The resultant polymers are useful as additives to tire rubbers to improve processability by reducing compound Mooney viscosity and reducing the shrinkage of various compound stocks.

  • Patent number: 5580930
    Abstract: Diene polymers having a high content of trans-1,4 addition and two distinct melting points in the ranges of 30.degree. C. to 60.degree. C. and 70.degree. C. to 130.degree. C. are useful as additives to tire rubbers to improve processability by reducing compound Mooney viscosity and reducing the shrinkage of various compound stocks.
