Abstract
The study of thermotropic liquid crystalline (LC) polymers with mesogenic side groups, which is intensively carried out nowadays widenes our knowledge about the structure of such systems. The synthesis and the identification of nematic and cholesteric polymeric liquid crystals’) as well as of some smectic phases such as disordered smectics S, and ordered smectics S, have already been reported2-@. Studying the polymeric mesophases, some authors claimed formation of an S, tilted smectic phase’). In this paper we report on the direct observation of the smectic C phase in LC polymers with polar mesogenic groups and on the results of the study of the structure by means of optical microscopy, X-ray analysis and differential scanning calorimetry. S, and S, phases were discovered in polyacrylates of the general formula:
