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.

1)通过过渡金属络合物的活性聚合：使用具有三联吡啶、吡啶-酰亚胺或环庚三烯酮配体的新型Nb、Ru、Co、Ni、Mo、Fe、Ti和W络合物来检查乙烯、异戊烯或聚合和它们的共聚。结果表明，Fe配合物对1，3-共轭二烯的聚合具有高的催化活性，Ti配合物对己内酯的聚合具有高的催化活性。Ni和Co配合物可得到高分子量的乙烯基型聚合物，而Mo配合物对乙烯基型聚合物的开环易位聚合具有高的催化活性。2）新型生物降解聚合物：我们研究了丙交酯与环状碳酸酯和己内酯的共聚反应，目的是以低成本获得具有良好机械性能的生物降解聚合物。结果表明，LA/CL/LA三维嵌段共聚物是一种优良的可生物降解高分子材料。3）高介孔活性炭的新功能：通过添加稀土金属和Mn化合物，不仅沥青，而且酚醛树脂和聚（偏氯乙烯/甲基丙烯酸甲酯）也可以制备所需的介孔炭。这些材料的有用性作为燃料电池，超级容量，和加氢催化剂进行了检查。
