Уважаемые коллеги, у кого есть доступ с СА, поделить, пожалуйста, рефератом на этот патент (FR1565700 A). Он существует, судя по всему, только на французском, качественно перевести его не получается, так м.б. сотрудники ISI еще в 1969 г. грамотно перевели

Abstract
1,4-Bis-(3,4-dicarboxybenzoyl)benzene (I) and its corresponding dianhydride (II) are prepd. and used for prepg. polyimides. Thus,70 g. AlCl3 was stirred for 30 min. with 135 ml. p-xylene, a soln. of 40 g. terephthaloyl chloride in 100 ml. o-xylene was added during 1 hr. at 7-12, the mixt. was heated 30 min. at 60 and 30 min. at 90, cooled, excess o-xylene eliminated in vacuo, 250 ml. H2O added gradually at .apprx.30, and the mixt. filtered to give 56.5 g. 1,4-bis(3,4-dimethylbenzoyl)benzene (III), m. 178. III (17.1 g.) was heated in an autoclave with 75 g. Na2Cr2O7.-2H2O and 350 ml. H2O for 5.5 hrs. at 250, cooled, the mixt. filtered, a soln. of 70 ml. 10N HCl and 60 ml. H2O added to the filtrate, and the mixt. filtered to give 15.1 g. I, m. 291 (H2O). I was converted to II, m. 278-9. by heating 9 hrs. at 200. II (4.31 g.) was added gradually to a soln. of 2.01 g. 4,4'-diaminodiphenyl ether in 29 g. anhyd. AcNMe2, the mixt. stirred 2 hrs. at 25, 10 g. of the resulting "collodion" was applied on a glass plate, the plate heated 1 hr. at 120, and cooled to give a transparent clear yellow film which was changed to a transparent clear brown film with good mech. properties by heating to 280 during 1 hr.
