4. CONCLUSIONS
Principally new concept for the design of LC photoalignment polymers
is proposed and experimentally proven by the use of methacryloylami-
noarylmethacrylates having two methacryloyl groups of different reac-
tivity. The more active O-methacryloyl group is subjected to
polymerization, while the less active NH-methacryloyl group under-
goes crosslinking reaction under photoirradiation. These materials
provide excellent LC alignment with low pretilt angle and widely var-
ied azimuthal anchoring excelling conventional materials by high
thermal stability. The materials have flexible design allowing further
optimization. Among the most important tasks is a search of new
synthesis roots giving increased yield of polymerization.
