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)有机稀土金属配合物催化合成单分散高分子聚合物:以[(SiMe3)3C]2Yb为引发剂,高产率得到高分子量、低多分散性的甲基丙烯酸甲酯全同立构聚合物。所得全同立构聚合物与高间规聚(甲基丙烯酸甲酯)混合生成立构复合物,其表现高温为220-260°C。己内酯与光学活性1-甲基三亚甲基碳酸酯或1,3-二甲基三亚甲基碳酸酯使用SmMe(C5Me5)2共聚 (THF)得到所需的高分子量和低多分散性的共聚物。2)介孔活性碳纤维的合成和性能:对含有Y(acap) 3 (0.3wa%)的碳纤维进行蒸汽活化,产生孔径>20*的介孔碳纤维。对直接染料、酸性或碱性模具等大分子的吸附行为表明,直接模具对直接黑19和直接黄12的吸附效果非常好。3)新型可生物降解聚合物的合成:使用有机金属引发剂将双缩肽与己内酯共聚,得到可生物降解聚合物,该聚合物在使用多种酶和活性污泥时表现出高降解性。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也得到可生物降解的聚合物。
