FIELD: chemistry.
SUBSTANCE: invention relates to production of high-strength polymer compositions using cycloaliphatic dioxides and can be used to produce binder for composite materials, coatings, adhesives and for other purposes. A polymer composition for producing binder and coatings based on epoxy resins and a nitrogen-containing curing agent, which is a product of reacting an amine with cycloaliphatic or cycloaliphatic-aliphatic dioxides obtained by direct epoxidation of unsaturated compounds, wherein during the reaction, a liquid or molten aliphatic, aromatic, cycloaliphatic or alkylene aromatic amine is fed into the reactor at the beginning, followed by a dioxide with respect to 3-20 times the molar excess of amine, followed by an acrylate and amino alcohol; the reaction mixture is stirred for 20-180 minutes at temperature of 30-180°C and then added to a mixture of epoxy resin with an active or passive diluent and a low-molecular aliphatic or aromatic hydroxyl-containing compound is added and stirred at T=15-95°C for 20-120 minutes.
EFFECT: invention improves processing properties of the polymer composition and raises the heat distortion temperature while simultaneously improving dielectric properties at temperature of 150-200°C and after exposure to hot and superheated water.
