Abstract
940,130. Polymerizing butadiene. FARBENFABRIKEN BAYER A.G. Jan. 16, 1962 [Jan. 18, 1961; July 22, 1961], No. 1561/62. Heading C3P. Polybutadiene which has a 1,4-Ci-structure of at least 80 % is made by polymerizing butadiene in solution or in bulk, in the presence of a catalyst which is obtained by the reaction of a lithium-aluminium tetra-alkyl of the general formula, Li Al (R 1 R 2 R 3 R 4 ) in which R 1 , R 2 , R 3 , and R 4 , represent aliphatic or cycloaliphatic radicals, with TiI 4 in a molar ratio of tetra-alkyl to TiI 4 of from 30: 1 to 1: 1. The TiI 4 may be partially replaced by TiCl 4 . The tetra-alkyl may be LiA2 (n-C 4 H 9 ) 4 , LiA2 (n-C 4 H 9 ). (i-C 4 H 9 ) 3 , Li Al (n-C 8 H 17 ). (n-C 4 H 9) 3 , Li Al (n-C 12 H 25 ). (C 2 H 5 ) 3 , or Li Al (CH 2 -CH 2 -cyclohexenyl)4. Specified solvents for solution polymerization are hexane, octane, petroleum ether, ligroin, hydrogenated diesel oil, cyclohexane, benzene, toluene, or methyl-naphthalene. The polymer is recovered using conventional techniques, and during the working up stabilizing agents and buffers may be incorporated in the polymer. Specifications 776,326 and 848,065 are referred to.
