FIELD: chemistry.
SUBSTANCE: invention relates to polymer materials meant for making articles via rotational moulding. The rotational moulding polymer material contains particles of a thermoplastic polymer or a mixture of thermoplastic polymers on whose surface there are silicon oxide particles whose size ranges between 1 and 1000 nm in amount of 0.001-0.1% of the total weight of the polymer material.
EFFECT: obtained material cuts on moulding time without considerable overheating of the molten mass with simultaneous removal of bubbles, as well as high mechanical strength of the articles.
