Abstract: Polyolefins (PO) are the largest-tonnage, available and demanded from the whole range of polymers produced by the industry. Therefore, the search for technical solutions aimed at simplifying the processing of polyolefins and creating new types of composite materials based on them is an urgent task. The physical and mechanical properties of filled polyethylene and polyamide compositions, determination of the melt flow rate by viscisometry methods, determination of bending strength by two-support bending methods, determination of Charpy impact strength were studied. The rheological characteristics of composite materials based on polyethylene with divalent metal phosphates have been determined. To obtain a composite material based on polyethylene, the content of bivalent metal phosphates was changed from 1 mass to 5 mass parts. Evaluation of the rheological properties of filled composites showed that with an increase in the content of metal phosphates, the fluidity of the compositions decreases, but the resulting compositions can be processed by injection molding. The data obtained show that the optimal compositions are those containing: 3 mass.h. metal phosphates.

Key words: polymers, composite materials, metal phosphates.
