FIELD: chemistry.
SUBSTANCE: invention relates to use of wax, based on chemically modified fatty acids - polyol esters as a lubricant for halogen-containing thermoplastic. Waxlike esters are prepared by A) metathetic oligomerisation of esters of polyols and fatty acids and B) subsequent hydrogenation of resultant reaction mixture, at least some of fatty acid units present in polyol esters being singly or multiply unsaturated. After step A or step B, volatile hydrocarbons are removed.
EFFECT: technical result consists in producing lubricants with sufficiently low volatility and high thermal stability under processing conditions.
