Syntheses and applications of interlocked polymers, polyrotaxanes, and polycatenanes, including corresponding oligomers are reviewed with emphasis on (i) synthesis of interlocked polymers consisting of interlocked structures as the monomer-linking units (genuine “topological” polymers), and (ii) application of the interlocked polymers in both bulk and molecular levels. Further, the review also refers...
Much interest has focused on the polymerization of isocyanide, which can be regarded as a stable N-substituted iminocarbene. Transition metal complexes have served as the most efficient and versatile initiators for the polymerization of isocyanides. This review covers a variety of studies carried out on transition metal mediated polymerization of isocyanides, from mechanistic studies to functionalized...
This review describes recent progress in the polymerization of conjugated and nonconjugated dienes catalyzed by transition metal complexes. Coordination polymerization of 1,3-butadiene produces cis-1,4-, trans-1,4-, syndio-1,2-, and iso-1,2-polymers which are obtained selectively by choosing the catalysts and the reaction conditions. Lanthanides catalyze polymerization of 1,3-butadiene to produce...
