<p>PURPOSE:To obtain a film for homogeneous orientation which is highly adhesive and resistant to heat and is stable with time by using a polyhydradiimide siloxane type high polymer film. CONSTITUTION:Electrodes are provided on substrates, and the soln. of the siloxane bond-contg. polyhydrazide acid-amide acid obtd. by reaction of carboxylic anhydride such as pyromellitic anhydride, dihydrazide such as isophthatic dihydrazide, diamine such as p-phenylene diamine and diaminosiloxane such as 1,3- bis(amino propyl)-tetramethyl disiloxane is coated on said substrates and electrode and is heated to cause dehydration and ring closure of said siloxane bond- contg. polyhydrazide acid-amide acid, whereby the polyhydradiimide-siloxane type high polymer film is formed. It is preferable to use arom. compds. for the above-mentioned compds. in terms of heat resistance.</p> |
