FIELD: chemistry.

SUBSTANCE: invention relates to composite materials. Method of producing composite material based on polyoligocyclopentadiene and wollastonite involves obtaining a liquid composition of wollastonite and oligocyclopentadienes by series of operations processing wollastonite solution silane finishing agent selected from a group, drying in vacuum at 90-110 °C, grinding and screening particles Wollastonite, characterised by ratio of length of particles to the thickness within 3…25:1, mixing of produced particles with dicyclopentadiene, heating to temperature of 155-210 °C, its holding at this temperature for 15-360 minutes and cooling to room temperature. Preliminarily mixed with the following components: at least one of polymer stabilizers selected from a group, at least one of radical initiators selected from a group, at least one of methacrylates, selected from a group and catalyst with structural formula, both in the patent claim, combines the produced mixture mixing components with the composition of wollastonite and oligocyclopentadienes, combined mixture components are in the following quantities the following, wt. %: polymer stabiliser or a mixture of stabilisers 0.1-3; radical initiator or a mixture of initiators 0.1-4; methacrylate or a mixture of methacrylates 0.3-20; catalyst 0.001-0.02; composition of oligocyclopentadienes and wollastonite - the rest. Combined mixture is heated to temperature of 50-320 °C and holding at this temperature for 1-360 minutes. Also disclosed is a composite material based on polyoligocyclopentadienes and wollastonite.

EFFECT: technical result is production of material with good properties.
