Abstract

1283327 Copolymerizing conjugated dienes and alkenyl aromatic compounds SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 19 April 1971 [16 April 1970] 26920/71 Heading C3P A process for the discontinuous copolymerization of at least one conjugated diene containing at most 5 carbon atoms and at least one alkenyl aromatic compound in a liquid diluent in the presence of an initiator based on lithium comprises (a) preparing a starting mixture of the diluent and a part of the total quantity of each monomer, (b) initiating copolymerization by contacting this mixture with the initiator and (c) keeping the monomer ratio in the reaction mixture constant during the copolymerization by adding the remaining part of each monomer. Specified monomers are butadiene, isoprene and piperylene; and styrene, α-methyl styrene, pmethyl styrene, #-methyl styrene, 1-vinyl naphthalene and 2-vinyl naphthalene. The initiator may be lithium or methyl, isopropyl, butyl, amyl, 2-ethylhexyl or phenyl lithium; ethylene, trimethylene or pentamethylene dilithium; 1,4-dilithiobenzene; 1,5-dilithiobenzene; 1,5-dilithionaphthalene or 1,3,5-trilithium pentane. The diluent may be an aliphatic, cycloaliphatic or aromatic hydrocarbon; and polymerization may be effected in the presence of cross-linking agents, e.g. divinylbenzene, and coupling agents, e.g. silicon tetrachloride, tin tetrachloride, hydrocarbon dihalides, ethyl acetate, ethyl acrylate, phenyl benzoate and diethyl adipate. Examples describe the copolymerization of butadiene and styrene in hexane/ cyclohexane mixtures in the presence of sec. butyl lithium and with the addition of silicon tetrachloride after the monomers.
