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.
