Document Type and Number:
Japanese Patent JP4205198
Kind Code:
B2
Abstract:
The present invention relates to polymers of the general formula I:in whichM<1, M<1', M<2 denote a recurring monomer unit from the group: acrylate, methacrylate, 2-chloroacrylate, 2-phenylacrylate;w, w<1, w<2 are molar fractions of the comonomers with 01<1 AND 0≤W2 <=0.5;S<1 and S<1', independently of one another, denote a straight-chain or a branched alkylene group -(CH2)r-;D, D', independently of one another, denote -O-;X, X', Y, Y' independently of one another, denote hydrogen;A, A', B, B' independently of one another, denote phenylene, which is C, C' unsubstituted or optionally substituted by fluorine, chlorine, cyano, alkyl, alkoxy or fluoroalkoxy;K and K', independently of one another, denote hydrogen, fluorine, chlorine, cyano;Z, Z', Z<1, Z<1' independently of one another, denote a single covalent bondt denotes an integer from 1 to 4;u denotes an integer from 1 to 3; andp, p', n, n' independently of one another, denote 0 or 1. The present invention also relates to the use of the above mentioned polymers as an orientation layer for liquid crystals and to their use in optical components.
