    摘要： AS CATALYSTS FOR POLYURETHANE PRODUCTION THESE ARE USED, INSTEAD OF STANNOUS SALTS AS SUCH, COMPLEXES OF STANNOUS SALTS WITH ORGANIC COMPLEXING AGENTS. EXAMPLES ARE COMPLEXES OF STANNOUS CHLORIDE OR, BETTER STANNOUS OCTANOATE OR THE LIKE WITH A KETONE, LACTONE OR AMINE. ONE ADVANTAGE OF USING THESE COMPLEXES IS THAT THEY HAVE SOME "DELYED ACTION" EFFECT, AVOIDING PREMATURE ACTION WITHOUT PREJUDICE TO THEIR FINAL EFFECTIVENESS. THEY MAY BE USED IN ASSOCIATION WITH KNOWN TERTIARY AMINE CATALYSTS, OR WITH UNCOMPLEXED TIN CATALYSTS.

    摘要： 1. A PROCESS FOR THE PREPARATION OF POLYURETHANE ELASTOMERS IN THE FORM OF GRANULES OR POWDERS BY REACTING AN ESSENTIALLY ANHYDROUS LINEAR DIHYDROXY COMPOUND, A DIISOCYANATE AND A CHAIN EXTENDER, THE IMPROVEMENT COMPRISING REACTING THE LINEAR DIHYDROXY COMPOUND WITH A MOLAR EXCESS OF DIISOCYANATE TO THE FORMATION OF A PREPOLYMER, SAID PRE-POLYMER BEING DISSOLVED IN A CHEMICALLY INERT AND ANHYDROUS SOLVENT, ADDING TO THE RESULTING SOLUTION THE CHAIN EXTENDER IN A SLIGHT MOLAR DEFICIT RELATIVE TO THE ABOVE-MENTIONED MOLAR EXCESS OF DIISOCYANATE, THEN ADDING A VOLTILE TERTIARY AMINE AS A CATALYST AND ALLOWING THE REACTION TO PROCEED UNTIL THE INITIALLY CLEAR SOLUTION GRADUALLY PASSES INTO A DISPERSION, AND THEN SUBJECTING SAID DISPERSION TO A STEAM TREATMENT WHILE VAPORIZING THE CATALYST AND THE SOLVENT, AND SEPARATING THE THE RESULTING POLYURETHANE FROM THE AQUEOUS PHASE OBTAINED.

    摘要： Provided as catalysts for the formation of cellular urethane polymers ranging from flexible to rigid foams, are beta-amino carbonyl compounds wherein carbonyl is present as an amido or carboxylic acid ester group and the beta-amino group is present as dialkylamino or an N-morpholino or N,N''-piperazino heterocyclic nucleus. Effective in the catalysis of the waterisocyanate reaction, these beta-amino amides and beta-amino esters are used with particular advantage in the manufacture of water-blown flexible foams, both molded and free-rise, including high-resilience and flame-retarded foam. The beta-amino carbonyl catalysts allow for the formation of foam products essentially free of the odor associated with amines such as Nethylmorpholine. In view of this highly desirable characteristic and their other beneficial properties, the catalysts of the invention are advantageously employed as direct replacements for N-ethylmorpholine in high-resilience and other foam formulations.

    摘要： 1. A catalyst-free process for the manufacture of foamed polyurethane products by substantially simultaneously interacting an organic polyisocyanate composition consisting essentially of a diarylmethane diisocyanate and 5-50% by weight of organic polyisocyanate having more than two isocyanato groups to the molecule, a liquid polyether having predominently secondary hydroxyl end groups containing from 3 to 8 hydroxyl groups per molecule and water in the absence of a catalyst for said interaction.

    摘要： A new catalyst for the acceleration of urethane polymerization consisting of a mixture of N,N-dimethyl-cyclohexyl-amine and Nmethyl-dicyclohexylamine has been found. The new mixture has unique characteristics that are not expected from its components taken alone.
