Abstract
Phenylpyrimidine derivatives were used to synthesize monomers, dimers and side group polymers. Only a few monomers and dimers show liquid-crystalline behaviour whereas almost all of the polysiloxanes, polyacrylates and polymetha-crylates prepared possess enantiotropic Hquid-crystalline phases. The structure of the main chain and of the mesogenic unit as well as the length of the spacer and of the terminal groups were modified. The relation between structure and phase behaviour is discussed.Keywords
