Novel Function Latent in Organometallic Compounds

1)过渡金属络合物的活性聚合：研究了以联吡啶、吡啶-亚胺或托普隆为配体的新型Nb、Ru、Co、Ni、Mo、Fe、Ti和W配合物的乙烯、降冰片烯或它们的聚合及其共聚反应。结果表明，铁络合物对1，3-共轭双烯的聚合具有很高的催化活性，钛化合物对己内酯的聚合具有很高的催化活性。2)新型生物可降解聚合物：我们考察了丙交酯与环状碳酸酯的共聚反应，以期以较低的成本获得力学性能较好的生物可降解聚合物。因此，LA/CL/LA组成的三维嵌段共聚物是一种优良的可生物降解的聚合物材料。3)高介孔活性碳的新功能：通过添加稀土金属和锰化合物，不仅沥青，而且苯酚树脂和聚偏二氯乙烯/甲基丙烯酸甲酯都能生成所需的介孔碳。考察了这些材料作为燃料电池、超大容量和加氢催化剂的用途。

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.
