Abstract

LC networks on the basis of methacrylate and dimethacrylate components were synthesized via bulk and precipitation copolymerization. Up to an amount of crosslinking component of 1 mol‐% a smetic A phase is observed. The networks with 3 and 5 mol‐% only show a nematic phase. From X‐ray diffraction an orientation of the smectic phase was observed that derives from surface effects or biaxial swelling. It was found that the orientation can be increased by multiple swelling/deswelling cycles.
