【Abstract】 Poly(arly ether sulfone ether ketone) PESEK and methyl substituted (Me-PESEK) were prepared by low temperature solution polycondensation of 4,4`-[sulfoneybis (1,4-phenylen) dioxy]dibenzoyl chloride (SODBC)(SODBC) with 4,4`-diphenoxydiphenysulfone(DPODPS),4,4`-di(2-methyl-phenoxy) diphenysulfone (o-Me- DPODPS) , 4,4`-di(3-methyl-phenoxy)-diphenysulfone(m-Me-DPODPS), 4,4`-di(2,6-dimethyl-phenoxy)-diphenysulfone(m-Me2-DPODPS)in 1,2-dichloro –ethane(DCE) and in the presence of anhydrous aluminum chloride(AlCl3) and N,N-dimethylacetamide(DMAc). The polymers were characterized by various analytical techniques, such as FT-IR, 1H-NMR, 13C-NMR, TG, WAXD. The results show that polymers having higher glass transition temperature (Tg) and initial decomposition temperature, and exhibited excellent solubility in common organic solvents.更多还原
