Abstract

FIELD: chemical technology. SUBSTANCE: prepolymer is prepared at 35-45 C by interaction firstly of polyisocyanate with polyhydroxypropylene glycol at mass ratio = (2.0-3.5):(0.15-0.25), respectively, followed by addition of toluylenediisocyanate, product of hydroxyalkylation of phosphorylated diol and urea at mass ratio = (4.5-6.0):1:(0.1-0.03), respectively. Stirring is carried out at 45 $$$ 5 C up to hydroxyl-groups disappearance. Product is used for making elastic formed polyurethane foam. EFFECT: improved method of producing. 1 tbl
