METHOD FOR PREPARING METAL-CONTAINING LUBRICANT FOR PREPARING MATERIALS MADE OF CHLORINE-CONTAINING POLYMERS Russian patent published in 2005 - IPC

FIELD: chemistry of polymers, chemical technology.

SUBSTANCE: invention relates to chlorine-containing polymeric composition that can be sued in manufacturing rigid, semi-rigid and soft materials. Method is carried out by interaction of alpha-branched saturated monocarboxylic acids of (C₁₀-C₂₈)-fraction with polyhydric alcohol at 180-230°C in the mole ratio = 1:(1-2) in the presence of metal oxides and their bi- and tri-component mixtures in the mass ratio MgO : CaO (or ZnO, BaO, CdO, PbO) = (0.25-1):(0.5-1) and MgO : CaO : ZnO (or BaO, CdO) = (0.5-1):(0.5-1), respectively, taken in the amount 0.5-2.0 wt.-% of the total reaction mass and without additional stages of neutralization, washing out, clearing and drying the prepared product. Ethylene glycol, glycerol, polyglycerol-vat residue after the glycerol distillation process can be used as a polyatomic alcohol. Invention provides preparing effective lubricants showing additional thermostabilizing capacity by ecologically safety technology, and expanding assortment of additives for polymeric articles also.

EFFECT: improved preparing method.
