FIELD: chemistry. ^ SUBSTANCE: invention relates to polymeric binding material for composite materials mainly made through wet winding or prepreg technique. Invention can be used as an impregnating compound, sealant, adhesive or coating. A 4,4'-bis-(glycidylamino)-3,3'-dichlorodiphenylmethane oligomer of formula C19H14N2O2 and binder based on said oligomer is obtained, including with addition of an organic solvent or active diluent (25-35%), and a curing agent ((0.5-1.1 pts. wt): 100 pts. wt composition).The disclosed oligomer hardens without using curing agents under the effect of high temperature. ^ EFFECT: oligomer has tensile strength of 248-264 kgs/mm2, modulus of elasticity of 11900-13100 kgs/mm2, glass transition point of 280-305 C. ^ 5 cl, 2 tbl, 18 ex |
