Rh Complexes Anchored on Inorganic and Organic Polymeric Supports: Heterogenous Catalysts for Polymerization of Substituted Acetylenes into High-Purity Polyacetylenes

Abstract

Via anchoring [Rh(COD)OCH3]2, [Rh(cyclodiene)acac] and [Rh(cyclodiene)Cl]2 on mesoporous molecular sieves and on porous polybenzimidazole heterogeneous catalysts of Rh-loading 0.3 ? 3 wt.% were prepared and used in acetylenes polymerizations .
