FIELD: chemistry.
SUBSTANCE: invention discloses a liquid moulding resin component for use in a reaction injection moulding process comprising reaction monomer liquid resin containing the polymerizable metathesis polymerization of cycloolefin, and a mass non-swellable mica, and the mass of non-swellable mica has an average particle size ranging from about 35 to about 500 mcm and a bulk density ranging from about 0.10 to about 0.27 g/ml. Also disclosed liquid resin system components for use in the reaction injection moulding process for producing a liquid resinous component for use in the injection moulding process and the moulded product from the resin.
EFFECT: obtaining a moulded product from the resin with high rigidity and low thermal expansion coefficient.
