Procedure

4-(methacryloyloxy) ethoxy-4'-methoxybiphenyl is prepared from 4-methoxy-4'hydroxybiphenyl by reaction with ethylenechlorohydrine in aqueous-alcoholic potassium hydroxide solution and subsequent azeotropic esterification with methacrylic acid in chloroform, catalyzed by p-toluol-sulfonic acid. This substance is heated for 8 hours to 65° C. in a benzene solution under nitrogen in the presence of 1 mol percent 2.2-azoisobutylonitrile. The reaction product is dissolved in chloroform and precipitated in a mixture of acetone and methanol. A solution of the liquid-crystal polymer in N-methyl-pyrrolidone is applied via a rubber roller to a glass substrate provided with a conductor structure and dried at 100° C.
