Abstract

1347088 Conjugated diene polymerization in an extruder BAYER AG 29 April 1971 [29 April 1970] 12075/71 Heading C3P Conjugated dienes are polymerized in the substantial absence of polymerization solvents, in the presence of a Zeigler-Natta catalyst, and in a double- or multiple-shaft self-cleaning screw extruder at - 20‹ to + 150‹ C. The monomer/ catalyst mixture may be pre-formed in an initial reactor prior to feeding to the extruder. The catalyst ingredients may be supplied in the form of solutions in the monomer. Plasticizing oils, polymerization inhibitors and stabilizers may be added to the product while still in the extruder. A diagrammatic representation of a suitable apparatus is provided. In examples, butadiene or isoprene are polymerized in the presence of a (C 2 H 5 ) 3 Al-TiCl 4 catalyst modified with I 2 (in butadiene monomer feed, forming diiodobutene in situ) or di-n-butyl ether. The products are treated with triethanolamine/2,6- di - t - butyl - p - cresol or 2,2<SP>1</SP>- methylene - bis- (4-methyl-6-t-butyl phenol).
