Abstract
The polyvinylcinnamate modified by the partial substitution of side chains for stearoyl fragments has been investigated. An oblique liquid crystal alignment with pretilt angle values controlled by the concentration of the stearoyl groups is obtained. The double degeneracy of an easy axis induced by polarized-light-irradiation technique is also verified.
