RADIATION-SENSITIVE POLYORGANOSILOXANE, METHOD FOR PRODUCING THE SAME AND LIQUID CRYSTAL ALIGNING AGENT

摘要

PURPOSE: Radiation-sensitive polyorganosiloxane is provided to be conveniently manufactured using a stable raw material and to obtain a liquid crystal alignment film having a good expression property of a pretilt angle when the polyorganosiloxane is applied to a liquid crystal alignment agent. CONSTITUTION: Radiation-sensitive polyorganosiloxane has a structure which is marked by chemical formula 3. In chemical formula 3, R is hydrogen or a methyl group and n is an integer of 1-10. R^1 is a group which is marked by chemical formula (R1-1) and R^2 is fluorine or a cyano group. In chemical formula (R1-1), R^I is an alkyl group having a carbon number of 1-40 or a monovalent hydrocarbon group having a carbon number of 3-40.
