Research Abstract

1) Living Polymerizations by Transition Metal Complexes : Ethylene, norbornene or polymerizations and their copolymerizations were examined using novel Nb, Ru, Co, Ni, Mo, Fe, Ti and W complexes having terpyridine, pyridine-imido or tropolone ligand. As a result, Fe complexes exhibit high catalytic activity for polymerizations of 1,3-conjugated dienes, and Ti compounds for caprolactone. Ni and Co complexes gave high molecular weight vinyl-type polymers of norbornene, while Mo complexes show high catalytic activity for ROMP of norbornene.
2) Novel Biodegradable Polymers : We examined the copolymerizations of lactide with cyclic carbonates ar caprolactone for the purpose of obtaining biodegradable polymers with good mechanical properties in a low cost. As a result, 3 dimensional block copolymers composed of LA/CL/LA was found to be excellent biodegradable polymer material.
3) New Function of High Mesoporous Activated Carbon : Not only pitches but also phenol resins and poly(vinyliden chloride/MMA) produce the desired mesoporous carbon by the addition of rare earth metal and Mn compounds. The usefulness of these materials as fuel cells, super-capacity, and hydrogenation catalyst were examined.
