METHOD FOR PRODUCTION OF ANTISTATIC POLYURETHANES Russian patent published in 1995 - IPC

Abstract RU 2028317 C1

FIELD: textile mechanical engineering. SUBSTANCE: bivalent copper chloride or trivalent iron chloride reacts with prepolymer (0.10-2.5% of prepolymer mass) during heating and in the presence of diamine and/or hydroxyl-containing compound in solvent medium. Polyurethane is characterized by higher hardness, elasticity and rupture strength. Metal chloride may be preliminarily dissolved in hydroxyl-containing compound. EFFECT: higher efficiency. 1 tbl
