Abstract
1358179 Diene polymers JAPAN SYNTHETIC RUBBER CO Ltd 23 Dec 1971 [26 Dec 1970] 59858/71 Heading C3P A diene elastomer is produced by polymerizing one or more conjugated dienes (e.g. butadiene, isoprene or piperylene) along or together with a vinyl aromatic hydrocarbon (e.g. styrene, α or # methylstyrene, 3 vinyl toluene or vinyl naphthalene) in the presence of an organolithium initiator (e.g. n-butyllithium) and an anionic surface active agent containing a group of the formula -SO 3 M or -OSO 3 M (where M is Na, K, Cs or Rb) and in a solvent comprising a mixture of (1) at least one aliphatic and/or alicyclic hydrocarbon, and (2) at least one alkyl substituted hydrocarbon said mixture containing 0À5 to 20% by weight of the alkyl substituted aromatic hydrocarbon. Extensive lists of monomers, catalyst components and solvents are given. In the examples butadiene is polymerized alone or copolymerized with styrene or isoprene using n-butyllithium and potassium or sodium dodecylbenzene sulphonate with as solvents cyclohexane containing toluene or n-hexane containing toluene, ethyl benzene, α- methyl naphthalene or o-xylene. The process may be continuous or batchwise and the catalyst components may be mixed in the polymerization reactor or before addition to it. Methanol, water and antioxidants may be added at the termination of polymerization.
