项目摘要

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.

1）通过催化有机稀土金属配合物的单分散性高分子聚合物的合成：当[（Sime3）3C] 2yb用作启动剂时，高分子甲基丙烯酸甲酯的高度同型聚合物以高分子量和低分散性获得高收益率。混合OG与高辛迪生型聚（甲基丙烯酸甲酯）产生的同骨聚合物产生立体杂种，该聚合物的高温为220-260°C. C. C. c.使用光学活性的1-甲基甲酸酯或1,3-二甲基苯甲酸甲甲苯甲甲基苯甲酸甲甲苯甲甲基苯甲酸甲甲苯甲酸苯甲酸甲酯（CRONEC）（CROLACONE）共聚于220-260 ﾟC。（THF）给出了高分子重量和低多分散性的所需共聚物。2）介孔活化碳纤维的合成和特性：含有Y（ACAP）3（0.3 wa％）的碳纤维的蒸汽机化产生中端碳纤维的孔纤维，其孔直径为> 20 * *。巨型分子（如直接染料，酸性或基本模型）的增加的吸附行为表明，直接死亡的直接黑色19和直接黄色12非常好。3）非常适合使用有机降解的剂量剂量的新型可生物降解聚合物合成新型的可生物降解聚合物：使用caprolactone deprolactone splude splude strude splude splude strude and splemers deprolactone dipsipeptides。丙酰酮的光学活性1-甲基和1,3-二甲基三甲基碳酸盐也提供了可生物降解的聚合物。
