Abstract

1516861 Catalyst for the polymerization of conjugated dienes MICHELIN ET CIE (COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELIN) 4 June 1975 [5 June 1974] 24148/75 Heading C3P [Also in Division C2] A catalyst for the homopolymerization of conjugated dienes or copolymerization thereof with an aromatic vinyl compound consists of (a) lithium or an organo-lithium compound, (b) a compound of barium or strontium and (c) an organometallic compound of a metal of Group IIB or IIIB of the Mendeleef Periodic Table. The polymers formed have a high trans content and low content of 1,2 linkages. In the examples butadiene or isoprene are homopolymerized or copolymerized with styrene or butadiene is copolymerized vinyl toluene or t-butyl styrene in cyclohexane, heptane or toluene using as catalyst n-butyl lithium; cinnamone or dibenzoylmethane barium, barium acetylacetonate, hydride, naphthenate or nonyl phenate and aluminium triethyl,-diethyl chloride,-ethyl dichloride or-ethyl sesquichloride or diethyl zinc.
