Synthesis of New Materials Using Organometallics

1)有机稀土金属配合物催化合成单分散高分子聚合物：以[（SiMe 3）3 C] 2 Yb为引发剂，高产率地合成了高分子量、低多分散性的甲基丙烯酸甲酯等规聚合物。所得全同立构聚合物与高间同立构聚（甲基丙烯酸甲酯）产生立体复合物，其显示220-260 ℃的高温。己内酯与光学活性的1-甲基三亚甲基乙基醚或1，使用SmMe（C5 Me 5）2（THF）的3-二甲基三亚甲基二胺得到所需的高分子量和低多分散性的共聚物。中孔活性炭纤维的合成与性能：将Y（acap）_3（0.3wa%）加入到活性炭纤维中，经水蒸气活化，得到孔径大于20 μ m的中孔活性炭纤维。3）新型生物降解聚合物的合成：以己内酯和二肽为原料，采用有机金属引发剂进行共聚反应，得到了具有高降解性的生物降解聚合物，该聚合物在几种酶和活性污泥的作用下表现出很好的降解性。光学活性的1-甲基和1，3-二甲基三亚甲基碳酸酯与己内酯的共聚反应也得到了可生物降解的聚合物。

1) Synthesis of Monodisperse High Molecular Polymers by the Catalysis of Organo Rare Earth Metal Complexes : when [(SiMe3) 3C] 2Yb was used as initiator, highly isotactic polymer of methyl methacrylate with high molecular weight and low polydispersity was obtained in high yield. The mixing og the resulting isotactic polymers with high syndiotactic poly (methl methacrylate) produces stereocomplexes, which show high temperature as 220-260ﾟC.The copolymerization of caprolactone with optically active 1-methyltorimethylenecarbonate or 1,3-dimethyltorimethylenecarbonate using SmMe (C5Me5) 2 (THF) gave desired copolymers of high molecular weight and low polydispersity.2) Synthesis and Property of Mesoporous Activated Carbon fiber : Steam invigoration of the carbon fiber containing Y (acap) 3 (0.3 wa%) produces mesoporous carbon fiber whose pore diameter is >20 *. the adsorption behaivior of giant molecules such as direct dyes, acidic or basic dies show that direct dies adsorps direct Black 19 and Direct Yellow 12 very well.3) Synthesis of New Type of Biodegradable Polymers : Copolymerization of dipsipeptides with caprolactone using organometallic initiators gave biodegradable polymers which show high degradability using several enzymes and activated sludge. Coplymerization of opticaally active 1-methyl and 1,3-dimethyltrimethylene carbonates with caprolactone also gave the biodegradable polymers.
