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.
