Sy. Lee et al., PHOTOINDUCED ORIENTATION AND MICROPATTERN IMAGING OF MALEIMIDE COPOLYMERS CONTAINING AZOBENZENE SIDE-GROUPS, Polymer bulletin, 40(1), 1998, pp. 1-8
Photo-induced birefringence properties of azobenzene containing maleim
ide copolymers P[DR1PMI-co-St] 1 and P[DR1MSt-co-PMI] 2 are investigat
ed. These polymers show reversible photo-induced birefringence and the
rate parameters for the induction and relaxation processes are obtain
ed. Photoimage patterns of the polymers with narrowest line width of 2
mu m are obtained. The micro patterns are relatively stable for over
a month at room temperature.
