摘要：

New optically active poly(ether imides) with a reduced viscosity of 0.14-0.34 dl/g were synthesized by the low-temperature polycondensation of aromatic diols with N,N'-[4,4'-carbonyl-bis(phthaloylimido)]-bis(L-leucine) dichloroanhydride in CHCl3 in the presence of triethylamine. Temperatures corresponding to the 5% weight loss of the produced polymers upon heating under nitrogen at a rate of 10 K/min fall in the 314-361°C range.
