FIELD: oligomer compounds. SUBSTANCE: product: new oligomers on the basis of bis-maleinimides and azomethines of the general formula where , , ; n = 2; a:b:c = (25-6):(2-6):1 with molecular mass 1300-4000, and composition material contains indicated oligomers. Binder is used at concentration 30-50 mas. p. per 100 mas. p. material. Synthesized oligomers can be used both independently as pouring compounds, coatings and for preparing composition material with hardening point 200 C and prolonged work ability at increased temperature (250-300 C) involving conditions with increased moisture. EFFECT: enhanced quality of oligomers. 3 cl, 2 tbl
