Notes:
Polyvinylpyridines activated by tris(π-allyl)chromium and by tetrakis (σ-allyl)molybdenum or tetrakis(σ-allyl)tungsten, complexed with tetrahydrofuran, were used for grafting with acrylonitrile. The products obtained, differing in the degree of branching, were characterized by various physical methods. Block copolymers of the types butadiene-acrylonitrile and styrene-oligobutadiene-acrylonitrile were synthesized by the use of tris(π-butadienyl)chromium as the initial active agent. Some molecular parameters of these block copolymers were established.
