Abstract
We have undertaken a systematic study of polymers whose chains are of such chemical composition and structure that liquid crystalline phases may reasonably be expected. Polyesters of general formula: have been prepared that give anisotropic liquid phases, probably of smectic C type.1 The characterization of the doubly homologous series of esters of formula: rose then as a necessary side problem. The calorimetric measurements made on the phase transitions of these compounds and the optical observations of their mesophases are in any case of intrinsic interest.Keywords
