The investigation of the catalytic activity and stereoselectivity of ligand 10 was also carried out under another standard set of K〓Fe 〓 conditions (〓/ligand/substrate=0.002: 0.01: 1). The AD reaction of seven olefins gave corresponding diols in 72～99% yield (except for ethyl cinnamate, 48%) and 91～99% ees, which was comparable to those obtained from the reactions using the commercial ligand 〓PHAL.

将单季铵盐手性配体10用于AD反应的另一个催化体系〓BuOH-H〓O/K〓Fe〓中考察其催化活性和立体选择性，在七种烯烃的AD反应中，〓、配体与底物的摩尔比为0.002：0.01：1时，化学产率为72～99％（肉桂酸乙酯除外，为48％），ee值为91～99.9％，与商品配体〓PHAL的催化结果相当。

It begins to inactivate when the temperature is beyond 40℃. However, CDH has the ability to resist high concentration of H2O2.CDH catalyze a typical reaction of double substrates and double products, which fits the Cleland'sPing-Pong nmechanism.

CDH具有很强的耐受过氧化氢的能力，在50mmol/LH2O2下保持12小时，仍保存近80%的活力，CDH催化的是一典型的双底物双产物反应，符合Cleland的兵乓反应机制。

It was found that the multifunctional monomer glycerol trilinoleate is a suitble coagent in this case. By adding DCP and GTL at the proper contents, the morphology and mechanical properties of PP/AS alloys were greatly improved.

在合适的GTL与DCP用量下，反应共混不但显著改善了PP/AS合金的相形态，而且提高了合金的力学性能，初步确立了聚丙烯共混物一步反应共混挤出增溶的方法。

When the sodium lauryl sulfate and p-octyl polyethylene glycol phenyl ether is used and its level in 3% and 6: 4 ratio, the polymerization process has the lowest coagulum and the highest monomer conversion. Higher reaction temperature and more level hydroxyl value lead to more coagulum, the latter also lead to larger particle size. The acid value has larger influence on viscosity and coagulum, there exist a best range. The emulsion particle size is larger for its hydrophilicity, most of its particles are connected together.

在含较高亲水单体的乳液聚合体系中，难以制得稳定的预乳化液，不能采用工业生产中常用的预乳化工艺，而只能采用混合单体直接滴加的方法；由于单体混合物的亲水亲油值较高，用阴离子型乳化剂十二烷基硫酸钠和非离子型乳化剂聚乙二醇辛基苯基醚混合，用量为单体总量的3％，且比例在6：4时，乳液聚合时具有最低的凝聚物含量和最高的单体转化率；乳液聚合反应温度升高，可以提高单体转化率，增加反应速度，但凝聚率相应提高；随着羟基单体含量的增加，聚合过程中凝聚率增加，聚合物乳胶粒平均直径增加；羧基单体有一个最佳的用量（2.6％），过高或过低凝聚率均提高；羧基含量对乳液的粘度有较大的影响，当羧基含量较低时，羧基含量增加，乳液粘度增加明显；含羟基乳液粒子由于含亲水基团较多，使得乳胶粒径增大，乳胶粒子大多数互相凝聚在一起，处于凝聚态。
