In DMSO, the polymerization of methyl methacrylate could be carried out efficiently. However the photopolymerization was inhibited in acetonitrile. It was ascribed to the complex formed between coumarin 1 and HTIB photolyzed to unreactive species after irradiation in acetonitrile.

在一般极性溶剂中如DMSO中能有效地引发甲基丙烯酸甲酯光聚合，而在电子受体性质的极性溶剂如乙腈中，光聚合反应受阻，这归结于香豆素1与羟基苯基碘鎓盐形成络合物，使得光反应后生成不具活性的产物。

Third, Polymerization behaviors of alkenyl substituted Cp Lanthanide complexes as Methyl Methacrylate polymerization catalysts were also studied.

Polyurethane hybrid emulsion modified by caster oil and arylate was synthesized with toluene diisocyanate, polycaprolactone glycol (PCL22ON), castor oil, and methyl methacrylate.

以聚醚多元醇(N22O)、甲苯二异氰酸酯(TDI-80)、蓖麻油(C.0)、甲基丙烯酸甲酯为主要原料，合成了蓖麻油改性的水性聚氨酯复合乳液。

The multi monomer of methyl methacrylate/styrene melt grafting onto atactic polypropylene was studied.

对多单体甲基丙烯酸甲酯和苯乙烯熔融接枝无规聚丙烯进行了研究。

For example, there is only local cooperative organization between polymer segments of atactic poly in the middle-sized solvent poly with molecular weight 200g/mol (PEG200). But for the stereo-regular isotactic polystyrene, pronounced content of 3〓 helix can be found in its middle-sized solvents.

例如，无规聚甲基丙烯酸甲酯在聚乙二醇（分子量为400）中分子溶剂中表现为链段的局部协同组织，而等规聚苯乙烯在邻苯二甲酸二辛酯、氯代十四烷等中分子溶剂中则出现相当含量的3〓螺旋构象。

It was found that both the conversion and the initiating efficiency of methyl methacrylate polymerization system were decreased in the presence of small amounts of addition inhibitions 2,4,6-trinitrophenol or Benzoquinone, the system exhibited some retardation characteristics; at the same time, the molecular weights of obtained polymers was small and the molecular weight distributions was narrow, it was suggested that this polymerization system exhibited some ""living""/controlled radical polymerization characteristics.

发现在甲基丙烯酸甲酯的普通自由基聚合体系中加入少量的加成型阻聚剂2，4，6-三硝基苯酚或1，4-苯醌时，体系转化率降低，引发效率降低，呈现出一定的缓聚性质：同时得到的聚合物分子量变小，分子量分布变窄，具有一定的&活性&/可控的特征。

The asymmetric polymerization of methyl methacrylate is carried out using the chiral binaphthyl crown ether macrocyclic compounds binding n-BuLi or t-BuOK as chiral initiator at -78℃.

以手性联萘冠醚为配体，络合n-BuLi，t-BuOK等有机金属化合物形成手性引发剂体系，初步探讨了甲基丙烯酸甲酯单体的聚合反应。

Various mole ratios of acrylonitrile and methyl methacrylate were used to copolymerize in aqueous solution by Redox and the copolymers were obtained. The copolymers containing MOCT were synthesized by adding MOCT before copolymerization. The copolymer were derived from the copolymerization of AN and MMA in 30L kettle and then were mixed with various contents of MOCT, the copolymer films were cast by solution of the copolymer containing MOCT.

本课题采用不同摩尔比的丙烯腈和甲基丙烯酸甲酯进行水相沉淀聚合，制备了AN／MMA共聚物；在聚合阶段加入正十八烷微胶囊，制得了正十八烷微胶囊含量不同的共聚物；选择合适的条件进行大釜聚合，得到共聚物后与不同比例的正十八烷微胶囊混合，通过流延制得正十八烷微胶囊含量不同的共聚物膜；并尝试进行了纺丝实验。
