| 摘 要： | Poly （ acrylonitrile-methyl acrylate） copolymer was synthesized by water depositing polymerization and has a typical feed ratio of 85/15. And then 1 - 3 wt% lauryl alcohol maleic anhydride （LAM） was adopted as stabilizer to mix with the acrylonitrile based copolymer. The mixtures were characterized by using Fourier Transform Infrared Spectroscopy （FTIR）, Nuclear Magnetic Resonance （1 H NMR ）, Gel Permeation Chromatography （ GPC ）, Differential Scanning Calorimetry （DSC）, optic microscope and Ubbelohde viscosimetryr etc. The melting point （Tm） and glass transition temperature （Tg） of the 85/15 AN/MA copolymer mixed with LAM all decrease with the increase of stabilizer content. The lowest Tg and Tm were 116.1℃ and 209. 1℃ respectively at the heating rate of 100℃/min when the content of LAM is 2 wt%. The 85/15 AN/MA copolymer mixed with 1 - 3 w t% LAM possess good thermal stability up to 30 min at 220 ℃.
