METHOD OF PRODUCING METAL-CONTAINING LUBRICANTS FOR PVC COMPOSITION Russian patent published in 2018 - IPC C10M103/06 C10M125/10 C10M129/04 C08K3/22 C10N30/02 

FIELD: chemistry.

SUBSTANCE: method of producing metal-containing lubricants for PVC-compositions is provided by the interaction of oleic or stearic acid with glycerol in the presence of magnesium oxide and another metal derived from the distillation of reaction water. As a derivative metal, calcium hydroxide is used, acid is poured to the mixture of glycerol and calcium hydroxide pre-heated at 110°C for 1 hour, and stripping of reaction water is carried out by azeotropic stripping with the use of toluene at 85-110°C, when the molar ratio of acid:glycerin:calcium hydroxide:magnesium oxide is 4:2:0.5:0.5.

EFFECT: simplification of the method of producing a metal-containing lubricant for PVC compositions and enhancing the properties of the lubricant in the polymer composition.
