Abstract
1531085 Catalyst system in anionic diene polymerization MICHELIN & CIE (COMPAGNIE GENERALE DES ETABS MICHELIN) 26 Feb 1976 [27 Feb 1975] 07677/76 Heading C3P Conjugated dienes are homopolymerized or copolymerized with one another and/or with a vinyl aromatic compound at 50 to 120 C. in the presence of a catalyst formed from (A) an organometallic compound of a Group IIIB element (boron, aluminium group) having the formula where Me<SP>1</SP> is an alkali metal atom, Me<SP>2</SP> is an alkaline earth metal atom, M is a metal of Group IIIB, R<SP>1</SP> to R<SP>3</SP> are alkyl or aralkyl, R<SP>4</SP> is alkyl, aralkyl, or XB where X is O, S, NB, where B is alkyl, aralkyl, or M(R<SP>5</SP>R<SP>6</SP>) in which R<SP>5</SP> and R<SP>6</SP> are alkyl or aralkyl, and (B) an electron-donor compound. The monomers are typically butadiene or butadiene/styrene, while exemplified catalyst components include (A) Ba[AlEt 4 ] 2 , Ba[AlEt 3 OR] 2 , where R is nonyl phenyl, Li(AlEt 4 ], Li[AlEt 3 OiPr], LiOAlEt 2 , Li[AlEt 3 OAlEt 2 ], AlEt 3 , and Li[BEt 3 Bu], and (B) tetrahydrofuran, methanol, water, lithium isopropylate, tetramethylethylene diamine, picoline, acetonitrile, acetone, diisobutyl sulphide, hexamethylphosphoramide, lithium isopropylate/barium nonylphenate mixture, potassium t-amylate, the lithium salt of diethylene glycol monoethyl ether and the lithium salt of diethylaminoethanol.
