Zhang, Mei-Lin; Wang, Xiao-Jun; Zhang, Gang; Long, Sheng-Ru; Yang, Jie published the artcile< One-pot Synthesis and Characterization of Poly(meta-aryl sulfide sulfone imide imide)>, Formula: C8H3ClO3, the main research area is polyimide polysulfone polythioether synthesis solubility thermal stability.
Poly(meta-aryl sulfide sulfone imide imide) (m-PASSII) was synthesized by one-pot process using 4-chlorophthalic anhydride, 3,3′-diamino di-Ph sulfone and sodium sulfide (Na2S· x H2O) as starting materials in N-methyl-2-pyrrolidone at atm. pressure. The intrinsic viscosity of m-PASSII was obtained with optimum synthesis conditions is 0.21-0.27 dL/g. The polymer and the separated intermediates which generated during the synthesis process were characterized by elemental anal., FT-IR spectrum, 1H-NMR spectrum, x-ray diffraction, DSC, TGA and dissolvability experiment The polymer is found to have excellent thermal performance with glass transition temperature (Tg) of 224° and initial degradation temperature (Td) of 441°. Moreover, the polymer is dissolvable in strong polar solvents.
Journal of Macromolecular Science, Part A: Pure and Applied Chemistry published new progress about Glass transition temperature. 118-45-6 belongs to class chlorides-buliding-blocks, and the molecular formula is C8H3ClO3, Formula: C8H3ClO3.
