| titleOfInvention | Increasing the reactivity of coupling homopolymers |
| abstract | There is disclosed a process for the preparation of elastomeric polymers which comprises contacting at least one conjugated diolefinic monomer selected from the group consisting of isoprene, piperylene, 2-ethyl-1,3-butadiene, 2,3-dimethyl--1,3-butadiene and 1,3-butadiene, mixed with at least one polyvinyl aromatic coupling compound selected from the group of o, m and p-divinylbenzene, 1,2,4-trivinylbenzene, 1,8-divinylnaphthalene, 1,2-divinyl-3,4-dimethylbenzene, 2,4-divinylbiphenyl, 3,5,4'-trivinylbiphenyl and 1,3,5-trivinylbenzene under solution polymerization conditions with an organolithium catalyst, in which the amount of polyvinyl aromatic coupling compound ranges from about 1.0 to about 6 vinyl groups per mole of active lithium catalyst used, in which the living polymer is treated with (A) a polar compound selected from the group consisting of ethylene glycol dimethyl ether (glyme), diethylene glycol dimethyl ether (diglyme), triethylene glycol dimethylether (triglyme), tetraethylene glycol dimethyl ether (tetraglyme), 2,3-dimethyoxybutane, N,N,N',N'-tetramethylethylene-diamine (TMEDA), tri-n-butylphosphine and hexamethylphosphoric triamide (HMPA), in which the molar ratio of the said polar compounds to the active lithium ranges from about 0.01/1 to about 20/1 or (B) a polar compound selected from the group consisting of tetrahydrofuran, diethyl ether, triethylamine, 1,4-diazabicyclo-2.2.2-octane (DABCO), p-dioxane, tri-n-butylamine and N,N'-dimethyl-piperazine, in which the molar ratio of the said polar compounds to the active lithium ranges from about 0.5/1 to about 100/1. |
