In this work,4-methoxylcinnamoyl chloride was reacted with a commercial hyperbranched polymer(Boltom～TM H30)to prepare a hyperbranched photosensitive polymer(H30-Ci).The polymer was characterized by UV absorption spectrum and ~1H- NMR spectrum.After processed by Linearly Polarized Polymerization(LPP)method,the spin-coated films of H30-Ci were used as photo-alignment layers to assemble liquid crystal(LC)cells containing nematic liquid crystal(5CB).The observation by polarized microscope showed that the H30-Ci blended with a linear polymer(BP-AN-Ci)photo-alignment layers could align LC molecules in a very uniform way.
