FIELD: production of composite materials. SUBSTANCE: proposed polymer composition comprises 100 mass parts of laprole, 100-140 mass parts of stabilized prepolymer on the base of laprole, 2.0-3.0 mass parts of mixture of dimethylaminomethyl phenols as vulcanizing agent and 60-140 mass parts of filler. Mentioned above prepolymer is stabilized by dialkylphosphite or dialkylchlorophosphite or by hydrogen chloride acid, its quantity being 0.05-0.1 mass parts per 100 mass parts of laprole. EFFECT: improved relative tensile strength and relative elongation.
