Abstract: A method of preparing polyurethane packaging foam for dispensing into a container in which an article is present to be packaged for shipping, wherein the temperature of the polyurethane foam being dispensed into the container is reduced, as is the maximum reaction exotherm temperature. The method involves reacting polymeric isocyanate and polyoxyalkylated polyol precursors in the presence of water as the blowing agent for the foam. A nucleating agent is present in at least one of the precursors and is present in an amount sufficient to reduce the dispensing temperature of the foam reaction product but also the exotherm as the reaction continues to completion. Incorporation of a nucleating agent into the isocyanate and polyol resin components results in a carbon dioxide blown polyurethane packaging foam preferably having a density of 0.2 lb./ft..sup.3 to 2.0 lb./ft..sup.3.

Abstract: The present invention relates to a method of producing flexible polyurethane foam having reduced discoloration which utilizes low molecular weight alkanes or mixtures thereof as auxiliary blowing agents. More particularly, the present invention relates to the use of auxiliary blowing agents which are linear or branched alkanes having boiling points above -50.degree. C. and below 100.degree. C.

Abstract: Carboxylated latex resins and neutralized carboxylated water-soluble polymers are crosslinked with aliphatic or cycloaliphatic polyfunctional polycarbodiimides or mixed aliphatic-aromatic polyfunctional polycarbodiimides.

Abstract: Preparing a flexible, polyurethane foam:(a) placing a polyol polyurethane foam-forming reaction mixture in a reaction zone and allowing the mixture to rise, thereby forming a partially cured cellular material,(b) applying a compressive force to the partially cured cellular material after the elapsing of a period of time after completion of the rise to thereby reduce the volume of the partially cured cellular material, and(c) removing the compressive force and completing the cure of the compressed cellular material.The cellular material has enhanced cushioning properties including a unique and superior feeling of comfort resulting from a soft touch yet with a deep firm support with an appropriate springiness to the foam. The polyol in the polyurethane foam-forming reaction mixture contains a mixture of(d) from 90-10 parts by weight of a polymer-polyol composition containing about 10-40% polymer solids, and(e) from 10-90 parts by weight of a base polyol having a molecular weight of at least 4500 up to 7000.

Abstract: Mixed aliphatic/aromatic polycarbodiimides can be prepared by first heating aliphatic mono- and diisocyanates with a phospholene oxide catalyst and then feeding the aromatic mono and/or diisocyanates in an inert solvent to the reaction mixture. These polycarbodiimides find use in a method for cross-linking carboxylated latexes.

Abstract: A fast curing foamable composition useful for the production of fabric-like materials comprises a resin or latex formulation and a mixture of a highly ethoxylated alkylphenol, an alkali metal N-alkyl sulfosuccinamate and an alkali metal alkyl sulfate.

Abstract: Acrylated organomodified silicone compounds are formulated into radiation-curable varnishes applied in thin films to the surface of uncured, oil-based ink prints in line with the printing operation. The coating cures to a tack-free high gloss surface.

Abstract: A class of materials termed acrylated epoxy silicones have been synthesized. In one of its simplest forms, the final product can be the reaction product of an epoxy silicone and acrylic acid. These novel materials can be used per se or in formulations as coatings compositions that are readily cured to yield solid, protective, high gloss films.

Abstract: Radiation-curable acrylated urethanes having a lower viscosity than heretofore achievable without dilution are produced by an improved process that involves first reacting a monohydroxy-functional acrylate with a polyisocyanate followed by the reaction of the product mixture produced with a polyol. The acrylated urethanes so produced are useful in radiation-curable coatings.
