Title: Catalyst systems for diene polymers and copolymers - comprising alkali metal deriv. of amine and solubilising agent
Inventor: MUELLER EBERHARD DR
IPC: C08F36/04
Filed: 1974-10-19
Abstract: Homo- or co-polymerisation of conjugated dienes in inert org. solvents is characterised by the use of an alkali metal deriv. of an amine in the presence of a solubilising agent as catalyst. Li alkyl or aryl can be used as catalyst but if a high mol. wt. prod. is reqd., amt. used must be small. Such Li cpds. are deactivated by unavoidable impurities in diene monomers or solvents used. Li derivs. of amines are not affected in this way but are very difficulty soluble in monomers and solvents usually employed. In presence of a solubilising agent, excess can be used and a constant concn. can be maintained in soln. so that reproducible results are easily obtd.
