Abstract

Block copolymers of formula (A)a(D)b(M)c, in which A is a vinyl aromatic block, D is a conjugated diene block, and M is a C3-13alpha-olefin block optionally including ethylene, a is 20-5000 and b is 1-10, are prepared by polymerising M in the presence of (i) a precursor polymer of formula (A)a(D)bLi and (ii) a titanium or vanadium halide. Certain block copolymers in which M is propylene are claimed per se. [GB2156368A]
