方法以三氯氧磷、氯化胆碱和甲基丙烯酸-2-羟乙基酯为原料，合成含PC基团的聚合单体-2-甲基丙烯酰氧乙基磷酰胆碱。

The effects of the dosages of initiators, emulsifier, organicsilicon and 2-Hyciroxypropyl acrylate on conversion and graft efficiency were studied. Moreover, the particle morphology, particle size distribution and glass transition temperature of latex were characterized by Transmission Electron Microscopy, size distribution analyzer and Differential Scanning Calorimetry.

考察了引发剂用量、乳化剂用量、有机硅用量、丙烯酸羟丙酯用量对硅－丙核／壳乳液转化率、接枝率的影响，并借助透射电镜、粒度分布仪和差示扫描量热仪分别对乳胶粒形貌、粒径分布及其玻璃化转变温度进行了表征。

The fabrication of fibers was attempted. The copolymers, the copolymers containing MOCT and the copolymer films containing MOCT were characterized by using Fourier Transform Infrared Spectroscopy, Scanning Electron Microscopy, Differential Scanning Calorimetry, Thermogravimetric Analyzer and X-ray Diffraction etc. The conclusions were summarized as following,1. The AN/MMA copolymers were testified that copolymerization of most AN and MMA occurred and the ratio of AN and MMA in copolymer was less than the ratio of monomers. With the increase of the contents of MMA, the viscosity of copolymer solution, molecular weight and decomposition temperature of copolymers increase.

通过傅立叶变换红外光谱、扫描电子显微镜、差示扫描量热分析、热重分析、X-射线衍射分析等测试方法对得到的AN／MMA共聚物、含有正十八烷微胶囊的共聚物以及共聚物膜等进行了测试和分析，得到如下的研究结论： 1、丙烯腈—甲基丙烯酸甲酯之间发生了聚合反应，共聚物的组成比略小于投料比；共聚物的粘度和分子量随着第二单体MMA加入量的增加有增大的趋势；第二单体加入量的增大使得共聚物的分解温度升高，通过热重分析证实当AN／MMA摩尔比为85／15时，共聚物的耐热稳定性较高。

Template copolymerization of acrylamide with acylic acid was carried out in the presence of polyallylammonium chloride as matrix in aqueous solutions.The various influences on the rate of polymerization were studied by dilatometer and electrical conductivity measurements.
