4,4'-BIS-(GLYCIDYLAMINO)-3,3'-DICHLORODIPHENYLMETHANE OLIGOMER AND POLYMERIC BINDER FOR COMPOSITE MATERIALS BASED ON SAID OLIGOMER Russian patent published in 2011 - IPC C08L63/00 C08G59/02 B29C70/16 B29C70/50 

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.
