Beschreibung
Zusammenfassung:	FIELD: chemistry. ^ SUBSTANCE: invention concerns lubricants for polyvinylchloride compositions which can be applied in production of rigid, semirigid and soft materials. Metal-containing lubricants are obtained in a single stage by interaction of oleic or stearic acid with glycerin at mol ratio of 1:1 in the presence of zinc or magnesium oxide or their mix at 0.25-1:0.25-1 mass ratio, in amount of 0.5-2.0 wt % of the total reaction mass, at 130-160°C for 4-5 hours. Process is performed until acid value of reaction mass is under 10 mg of KOH/g. ^ EFFECT: simple, cost-effective method with increased output of target product, reduced temperature and duration of synthesis; lubricant for polyvinylchloride ensures good melt fluidity and high heat resistance of polymer composition due to the presence of zinc and magnesium carboxylates in lubricant composition. ^ 3 cl, 2 tbl
