Summary The synthesis of liquid crystalline side chain A-B blockcopolymers, prepared by living anionic polymerization in combination with a polymeranalogous reaction is reported. Thereby the A-block was formed from a non mesogenic monomer (styrene, butadiene and n-butylmethacrylate) and the B-block from a monomer with a lateral active group (2-(trimethylsiloxy)-ethylmethacrylate), used for introduction of the side chain mesogens (cholesterylformyl- and 2-(4-[5-hexylpyrimidin-2-yl]-benzoyloxy)-groups). The obtained copolymers show mostly phase separation phenomenons. In dependence of the content of LC side groups a mesomorphic behaviour was observed.
