HIGH-MOLECULE POLYETHEROPOLYOLES OF VERY WEAK ODOUR, METHOD OF OBTAINING THEM AND THEIR APPLICATION IN OBTAINING POLYETHEROPOLYOL-BASED POLYMERS, COSMETIC PRODUCTS AND PHARMACEUTIC PREPARATIONS

摘要

Low-odour mono- and polyfunctional polyether polyols (I) are claimed, where (I) have a molecular wt. of 750-18,000 and a Hoeppler viscosity (DIN 53015) of 40-25,000 mPa.sec at 25 degrees C and contain less than 1.5 ppm 2-methyl-2-pentenal, less than 1 ppm allyl alcohol, less than 15 ppm allyloxypropanol, less than 50 ppm dipropylene glycol allyl ether and less than 1 ppm propionaldehyde.
