Nm. Geller et Ss. Skorokhodov, SYNTHESIS OF POLY[4,4'-ALKYLENEBIS(OXYCARBONYLPHENYL) TEREPHTHALATES]CONTAINING SHORT BRANCHED FLEXIBLE LINKS, Russian journal of applied chemistry, 69(9), 1996, pp. 1385-1388
A series of poly[4,4'-alkylenebis(oxycarbonylphenyl) terephthalates] a
re prepared by polycondensation of terephthaloyibis(4-oxybenzoyl chlor
ide) and short-chain branched glycols. The effect of substituents in t
he alkylene bridge on the temperatures of phase transitions in the mes
omorphic polymers prepared is studied.
