| titleOfInvention | Preparation of interpolymers of conjugated diolefins and internal olefins |
| abstract | A copolymer of a conjugated diolefin and an internal olefin, and optionally benzene or an alkyl-substituted benzene, wherein some at least of the diolefin units exhibit a cyclized structure are made by copolymerizing the monomers in the presence of a catalyst formed from (A) an organo-aluminium compound of the formula <FORM:1120415/C3/1> where R1 is an aliphatic, araliphatic, or aryl hydrocarbon radical and R2 and R3 are as R1 and additionally hydrogen, (B) a reducible compound of T1 or V and (C) an oxygenated compound selected from organic peroxides, and hydroperoxides, H2O2, H2O, O2, ketones, aldehydes, quinones, and alcohols, wherein the mole ratio of (A) to (B) is at least 0.2/1 and not substantially greater than 5/1 and the atomic ratio of the oxygen in compounds (C) to aluminium is greater than 0.5/1 but does not substantially exceed 4.0/1, and optionally an aromatic hydrocarbon. Specified dienes are isoprene, butadiene, piperylene, 2-ethyl- and 2,3-dimethyl-1,3-butadiene. Specified internal olefins are 2,3-dimethyl - 2 - butene or -2- pentene, 3,4 - dimethyl - 3 -hexene, 2 - methyl - 2 - pentene, or -2 - butene, 3 - methyl - 2 - pentene, 4 - methyl-2 - pentene, 2 - butene, 2 - hexene, 2 - pentene and 3-hexene. The polymerization may be effected in bulk, or in an inert solvent or diluent. In the example, isoprene and 2,3-dimethyl-2-butene dissolved in n-pentane are copolymerized in the presence of a catalyst consisting of cumyl hydroperoxide, triisobutyl-aluminium, and TiCl4. The reaction is terminated by the addition of tetraethylene pentamine, and an aromatic amine as antioxidant. The Specification contains lists of suitable catalyst components. |
