| Abstract: | High molecular weight SMA copolymer of styrene and maleic anhydride was prepared by non-aqueous dispersion copolymerization in the presence of a new steric stabilizer. Its average molecular weight determined by GPC method is high up to 460000, and size range of the dispersed particles is narrow. The factors affecting particle size, molecular weight, yield were investigated by the concentrations of monomers, the reaction temperatures, the amounts of initiator and stearic stabilizer. The molecular structure of SMA was characterized by IR, NMR, DTA, HPLC, TEM and element analysis. |
