Abstract

Methyl methacrylate was used as a main monomer in this paper. Firstly poly(methyl methacrylate) (PMMA) was synthesized by bulk polymerization of methyl methacrylate(MMA) in mold. Subsequently MMA was copolymerized with acrylonitrile (AN) and styrene (St) respectively in mold. The as-prepared products were tested by tensile and impact test. The results of test show that with the increase of the AN content in the copolymer, the tensile strength of the copolymer showed a downward trend for the internal defects after rising first for the forming of intermolecular hydrogen bond. The impact strength of the copolymer showed a rising trend for the formation of hydrogen bonds. Meanwhile, with the increase of the St content, the tensile strength of the copolymer showed a rising trend for the introduce of strong rigidity benzene. The impact strength of the copolymer increased first for the rigidity of benzene pendant group and then decreased for the decline accumulation degree of molecular chain
