FIELD: polymer production.
SUBSTANCE: manufacture of polymer composite products such as casing pipes, tanks and cylinders. A method for producing a binder based on dicyclopentadiene (DCPD) for the production of composite products by winding includes the preparation of A and B components and their mixing until the viscosity of the binder reaches 120-1000 cP. A component is obtained from a reaction mixture comprising DCPD, a thixotropic thickener selected from silica and/or ethylene-propylene rubber, a hydroxy-functionalized olefin monomer, and toluene diisocyanate and/or methylenediphenyl diisocyanate. B component is prepared by mixing a thermally activated ruthenium metathesis polymerization catalyst with methacrylic monomer and a radical initiator. A binder based on DCPD is also proposed.
EFFECT: increasing of the viscosity of the binder, as well as the strength, heat resistance and resistance to oil and mineral acids of polymer composite products made using the proposed binder.
