| titleOfInvention | Process for the production of low molecular weight liquid unsaturated polymers |
| abstract | Liquid unsaturated polymers of average molecular weight from 500 to 5000 and viscosities of 50 to 500 centipoises (measured at 50 DEG C. in a Hoepler ball fall viscometer according to Haake) and derived from conjugated diolefines with or without alpha-olefins, are made by polymerizing diolefines with or without alpha-olefines in the presence of a catalyst consisting of diluent-soluble nickel compounds and organo-aluminium halides of the formula RnAlX3- n in which R is an alkyl, phenyl, or aralkyl radical, X denotes halogen, and n a number from 1 to 2, and 0.005 to 0.15 times (with reference to the weight of the monomers used) of a vinylcyclo-olefine having six to eighteen carbon atoms. The diluent may be a hydrocarbon or a chlorinated hydrocarbon. The inorganic salts of nickel are rendered soluble in inert diluents by treatment with alcohols, amines, or ethers. Aluminium hydrides may be used mixed with the alkyl aluminium halides. The vinylcyclo-olefine may be 1-vinyl-4-methyl-cyclohexene - (3), 1 - vinylcyclopentene - (3), 1 - vinylcyclobutene - (2), limonene, 3,5 - diethyl - 1 - vinylcyclopentene - (2), or divinylcyclohexene. The diene may be butadiene, isoprene, 2,3 - dimethylbutadiene - (1,3), pentadiene - (1,3), 2 - ethylbutadiene - (1,3), 4 - methylhexadiene - (1,3), 2 - methylpentadiene - (1,3), 2 - isopropylbutadiene - (1,3), or octatriene-(1,3,7). The alpha-olefin may be styrene. The polymers are recovered by conventional techniques. |
