Two series of poly(ether amide)s, ! and II, were prepared by direct polycondensation from 4,4'-diacrylic acid<t, to-diphenoxyalkanes and 4,4'-dicarboxyl-~, to-diphenoxyalkanes with diamines. The phase behaviour of these polymers was studied by differential scanning calorimetry and optical polarizing

Three series of the thermotropic liquid crystalline copoly(imide-ester)s were prepared by direct polycondensation. The first two series of the copoly(imide-ester)s were synthesized from N-(4-carboxyphenyl) trimellitimide with N,N-di( hydroxypropyl) pyromellitic diimide and various aromatic diols. Th
