Synthesis and Characterization of Liquid-Crystal Photoresist
A thermotropic liquid crystal polymer with photosensitive groups (liquid crystal photoresist), copoly (4-methoxyphenyl 4’-(2"-acryloyloxy ethoxy) benzoate (MPAEB) -4-vinylbenzyl cinnamate (VBC)) was prepared, and its thermal behavior was characterized by a differential scanning calorimetry. The copolymer exhibited a liquid crystal mesophase between approximately 70-degrees-C and 120-degrees-C. In the mesophase, poly(MPAEB-VBC) (85/15) had a higher photo-crosslinking ability than that at room temperature and at 140-degrees-C, where the copolymer exhibited the isotropic phase. It was found that the liquid crystal photoresist had a high crosslinking ability owing to alignment of its photosensitive groups.
