Abstract
1312854 Non-linear asymmetric block copolymers SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 21 May 1971 [22 May 1970] 16263/71 Heading C3P A block copolymer has the formula where C is a residue of a multifunctional coupling agent, A is a non-elastomeric polymer block, B is an elastomeric polymer block, D is further polymer block which is non-identical with the unit (A-B-)-, x is an integer of at least three, and n is 10-65% of x. It is obtained by forming a mixture of living AB and D polymers and coupling with a polyfunctional coupling agent. The copolymer may be hydrogenated using mild conditions and a Zeigler-type catalyst. In the example a copolymer of formula is obtained by polymerizing styrene in the presence of sec-butyl lithium in cyclohexane, adding a butadiene, cyclohexane, isopentane, sec-butyl lithium mixture and continuing polymerization to form block- and homo-polymer chains in a 3 : 1 ratio, and finally coupling with dimethyl adipate.
