Abstract
1,171,597. Stereoregular butadiene-styrene copolymers. TEXAS-U.S. CHEMICAL CO. 18 July, 1968 [4 Aug., 1967], No. 34416/68. Heading C3P. A substantially linear, random styrene-butadiene copolymer having a styrene content of 2 to 55% by weight and wherein at least 90% of the butadiene units are in the cis-1,4.conflguration and having an intrinsic viscosity of from 1 to 4 measured in toluene are obtained by copolymerizing under solution conditions in the presence of an iodine-containing catalyst comprising (i) at least one ether-free organomagnesium compound of the formula RMgX or R 2 Mg, where X is halogen and R is a C 1 _ 30 hydrocarbyl group, and (ii) a titanium tetrahalide at- 10‹ C. to 150‹ C. The polymerization is suitably carried out in a hydrocarbon solvent, the monomers purified by contact with alumina, and the polymerization terminated with alcohols, amines and antioxidants. The copolymers may be fractionated using benzene/isopropanol. In the examples, copolymerization is carried out in the presence of (C 6 H 5 ) 2 Mg/C 6 H 5 MgCl (3-19) or C 12 H 25 MgBr (1 and 2) together with TiI 4 in all examples.
