Abstract

Novel thermostable polymers are prepd. by heating at >=180 degrees C a mixt. of an imine of formula (I) B(N=CR-G)m (I) (where m >=1; B is m-valent is not >50C organic gp. which is bonded to the imide gp(s) by one or more C atoms belonging to one or several benzene rings; G is not >35C organic gp. G' bonded by a C atom of a benzene ring is a gp. G'-CR=-B1; is as B or if m = 2 may be a gp. G'-N-B2-(N=CR-G'-CR=N-B2)w-Q; G' is not >35C divalent gp. with its free valencies on 2C atoms of 1 or 2 benzene rings; B2 is a divalent gp. B; Q is N=CR-G'-CRO or NH2; R is H or a is not >35 C organic gp. or forms a divalent gp. with G1; w is 1-10) with a polyisocyanate of formula (II) E(NCO)s (II) (where s is >=2; E is an S-valent is not >35C organic gp. bonded to the NCO gps. via C atoms of one or several benzene rings). Ratio imine:NCO gps. is pref. 0.2-5. The imide-isocyanate polymers have good mechanical and electrical props. and are chemically inert at 200-300 degrees C. They may be used for plate or tube form insulators for transformers and self-lubricating gears, rings and supports. Maleimide-contg. polymers are used similarly. Suitable starting materials are e.g. (I) benzylidene-amino benzene; bis-(4-benzylidene-amino phenyl) methane, propane, sulphone, and ether; 2,6-bis-(benzylidene-amino), (salicylideneamino)-, and (furfurylideneamino)-pyridenes; and polyimines prepd. by condensing terephthaloaldehyde with bis-(4-aminophenyl)-methane; (II) p-benzene diisocyanate; 2,4- or 2,6-TDI, 4,4'-diisocyanatodiphenyl, diphenyl methane and diphenyl ether; naphthalene, 1,5-diisocynate; and polyarylene polyisocyanates derived from aniline-HCHO condensate (III) bis-maleimide and polyarylene polyimides derived from aniline-HCHO condensates.
