Research on Structure and Properties of a Novel Type of Poly( Ester-Imide)
A diacid monomer was prepared from trimellitic anhydride and aminobenzoic acid,and a novel poly(ester-imide) was synthesized through the diacid monomer and the 1, 4-butanediol.The structure and chemical resistance, intrinsic viscosity and thermal property and crystallization of the poly(ester -imide) were characterized by FT-IR spectra,various organic solvents,a capillary Ubbelohde viscometer,differental scanning calorimetry (DSC) and thermogravimetric analysis (TGA) and crystallization rate instrument.The results showed that the poly(ester-imide) has excellent chemical resistance and thermal property,its intrinsic viscosity is 0.46dL/g,it has high glass transition temperature (Tg) and relatively low melting temperature (Tm).Moreover,the novel poly(ester-imide) has obvious crystallization and excellent property to spin into fibers.
