Manufacture of reaction products of polyisocyanates with ethylene oxide addition products

Claim 1

A PROCESS FOR THE MANUFACTURE OF A HIGH MOLECULAR SURFACE-ACTIVE POLYURETHANE FROM AN ORGANIC POLYISOCYANATE AND AN ALKYLENE OXIDE ADDITION PRODUCT AS THE SOLE REACTANTS, WHEREIN AN ORGANIC POLYISOCYANATE CONTAINING ONLY ISOCYANATE GROUPS AS REACTIVE FUNCTIONAL GROUPS IS REACTED WITH A POLYGLYCOL ETHER CONTAINING AN ALIPHATIC HYDROCARBON RADICAL OF AT LEAST 8 CARBON ATOMS AND ONLY ONE FREE HYDROXYL GROUP AND HAVING A MOLECULAR WEIGHT OF AT LEAST 1000, AND WHICH POLYGLYCOL ETHER DERIVATIVE IS OBTAINED BY REACTING AN ALKYLENE OXIDE HAVING AT MOST 3 CARBON ATOMS WITH A MEMBER OF THE CLASS CONSISTING OF MONOALCOHOLS CONTAINING AN ALIPHATIC HYDROCARBON RADICAL OF AT LEAST 8 CARBON ATOMS, ALKYLATED MONOPHENOLS CONTAINING AN ALIPHATIC HYDROCARBON RADICAL OF AT LEAST 8 CARBON ATOMS, MONOMERCAPTANS CONTAINING OF ALIPHATIC HYDROCARBON RADICAL OF AT LEAST 8 CARBON ATOMS, MONOCARBOCYLIC ACIDS CONTAINING AN ALIPHATIC HYDROCARBON RADICAL OF AT LEAST 8 CARBON ATOMS AND SECONDARY MONOAMINES CONTAINING AN ALIPHATIC HYDROCARBON RADICAL OF AT LEAST 8 CARBON ATOMS, SAID POLYISOCYANATE CONTAINING AT LEAST 1 ISOCYANATE EQUIVALENT PER MOL OF ALKYLENE OXIDE ADDITION PRODUCT.
