POLYAMIDE-BASED PHOTOREACTIVE POLYMER WITH EXCELLENT VOLTAGE HOLDING RATIO AND LIQUID CRYSTAL ORIENTATION AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A polyamide-based photoreactive polymer is provided to have excellent orientation and electric performance, thereby providing an alignment film and a liquid crystal display device with superior performance.;CONSTITUTION: A polyamide-based photoreactive polymer comprises a repeating unit represented by chemical formula 1. A manufacturing method of the polyamide-based photoreactive polymer comprises a step of forming the repeating unit represented by chemical formula 1, by reacting polysuccinimide which includes a repeating unit represented by chemical formula 3, under the presence of a compound represented by R1-O-(CH2)n-NH2. In the chemical formulas; m is 10-1000; n is 2-6; R1 is a photoreactive functional group of a cinnamate-based functional group, azo-based functional group, or coumarin-based functional group.;COPYRIGHT KIPO 2013
