Patent number: 4228266Abstract: A novel copolymer resin having excellent compatibility with rubber and plastics, stable to air, easily soluble in the hydrocarbon solvents and free of gel, said resin being obtained either (1) by copolymerizing one or more of the monomeric substances selected from the group consisting of cyclopentadiene, dicyclopentadiene and alkyl-substituted compounds thereof and one or more of the substances selected from the hydroxystyrene derivatives, or (2) by copolymerizing one or more of the monomeric substances selected from the group consisting of cyclopentadiene, dicyclopentadiene and alkyl-substituted compounds thereof, one or more of the substances selected from the codimers of cyclopentadiene and/or alkyl-substituted compounds thereof and chain conjugated diolefins having 4 to 5 carbon atoms, and one or more of the substances selected from the hydroxystyrene derivatives. There are also provided compositions comprising said resin and rubber or thermoplastic high-molecular weight substances.Type: GrantFiled: August 21, 1978Date of Patent: October 14, 1980Assignee: Sumitomo Chemical Company, LimitedInventors: Ken-ichi Kudo, Yoshihiko Kitagawa, Teruhisa Koyama, Akira Takata, Shuichi Kanagawa, Tetsuo Yamaguchi

Patent number: 4226965Abstract: Polymerization or copolymerization of the starting monomers is carried out in a hydrocarbon medium in the presence of a catalyst containing an alkylaluminium chloride compound, a trialkylvanadate and an alkoxyderivative of titanium, or zirconium, or hafnium. The method of the present invention makes it possible to considerably increase the polymerization rate and degree of conversion in the preparation of polymers and copolymers of higher .alpha.-olefines. The resulting polymers of higher .alpha.-olefines have a stereoregular structure with a high degree of crystallinity which is manifested in an increased melting point of the resulting polymer.Type: GrantFiled: September 28, 1978Date of Patent: October 7, 1980Inventors: Vasily A. Grigoriev, Zinaida V. Arkhipova, Gurgen A. Balaev, Nikolai G. Bakajutov, Vera I. Vysotskaya, Arkady V. Polyakov, Vitaly M. Zapletnyak
