Synthesis of Terpolymers from 4,4'-Diphenoxydiphenylsulfone, 4,4'-Diphenoxybenzophenone and Terephthaloyl Chloride
Abstract:
A series of terpolymers(DPODPS/DPOBP/TPC) were prepared by low temperature solution polycondensation of 4,4'-diphenoxydiphenylsulfone(DPODPS), 4,4'-diphenoxybenzophenone(DPOBP) and terephthaloyl chloride(TPC) in 1,2-dichloroethane in the presence of AlCl3 and NMP. IR、WAXD、TG and DSC techniques were used to study the general properties of the copolymers. The results showed that the Tg and Td of the copolymers increased with the increase in DPODPS content, the Tm and Tc of the copolymer decreased with increase in DPODPS content. The terpolymers obtained have lower melting temperatures than polyether ketone ether ketone ketone(PEKEKK), and their heat-resistance properties are as good as that of PEKEKK.
