Abstract: Polyurethane foams are prepared in the presence of a compound containing the grouping
WHEREIN R1 and R2 are the same or different alkyl, cycloalkyl, alkoxyalkyl, alkenyl or aralkyl radicals or are members of a common cycloaliphatic or heterocyclic structure when the silicon atom is part of a silane or lower polysiloxane grouping; or R1 has the above meaning and R2 denotes an hydroxylalkyl or aminoalkyl group attached to the silicon atom through the oxygen or nitrogen atoms respectively. The invention contemplates complexes or mixtures of these compounds with organic metallic compounds also as catalysts. In addition new activator mixtures containing these catalysts are contemplated.

Abstract: An N-(perfluoroalkyl-sulphonyl)-carbamic acid ester of a polyalkylene oxide of the formula:

in which: RF is a perfluoroalkyl radical of up to 20 carbon atoms, R1 is hydrogen, alkyl, hydroxyalkyl, cycloalkyl, alkenyl, aralkyl, or

R2 is a polyoxyalkylene radical, and R3 is alkyl of up to 8 carbon atoms, alkenyl, aralkyl or

The compounds are produced by reacting a perfluoroalkylsulphonamide with a chloroformic acid ester of a polyalkylene oxide in the presence of an acid binding agent. The products are useful as surfactants in making polyurethane foams.

Abstract: A PROCESS FOR THE PREPATATION OF NON-VOATALE, LOW MOLECULAT WEIGHT MONO-AND POLYISOCYANATES CONTAINING TERTIARY AMINO GROUPS, WHICH CONTAIN ONE MORE HYDROXYL GROUPS AND/OR ONE OR MORE SECONDARY AMINO GROUPS AND/OR ONE TO THREE PRIMARY AMINO GROUPS ARE REACTED IN KNOWN MANNER WITH AN EXCESS OF AN ALIPHATIC, CYCLOALIPHATIC OR ARALIPHATIC DISOCYANATE. AT LEAST THREE MOLS OF DIISOYANATE BEING USED FOR ONE OF THESE GROUPS WHICH REACT WITH ISOCYANATES, AND THE EXCESS DISOCYANATE IS COMPLETELY REMOVED BY CONTINUOUS FLOW DISTILLATION AND/OR THIN LAYER DISTILLATION UNDER REDUCED PRESSURE AT TEMPERATURES OF 80 TO 200*C.

Abstract: A PROCESS IS PROVIDED FOR THE PRODUCTION OF POLYURETHANE FOAMS FROM POLYISOCYANATES, ORGANIC COMPOUNDS WHICH CONTAIN AT LEAST TWO ACTIVE HYDROGEN ATOMS, BLOWING AGENTS, CATALYSTS, SUBSTANCES WHICH PREVENT DISCOLORATION IN THE CORE OF THE FOAM AND, IF DESIRED, OTHER ADDITIVES, WHEREIN DISCOLORATION PREVANTATIVE IS A 6-HYDROXYCHROMAN OF THE GENERAL FORMULA:

2-R2,2-R3,3-R4,4-R5,6-HO,7-R1-2H-CHROMAN

IN WHICH R1 IS HYDROGEN, AN ALKYL RADICAL, A CYCLOALKYL RADICAL OR AN ARALKYL RADICAL CONTAINING FROM ONE TO 9 CARBON ATOMS, AND R2, R3, R4 AND R5 ARE THE SAME OR DIFFERENT HYDROGEN OR LOWER ALKYL GROUP HAVING FROM ONE TO 4 CARBON ATOMS.
