摘要： Flexible polyurethane foams having improved properties and made from modified polyether polyols are described. The polyether polyols are modified with adducts of epoxy resins, such as the diglycidyl ether of Bisphenol A, and diamines, such a polyoxypropylenediamine. The resulting modified polyether polyols have a molecular weight of from about 2,000 to 7,000. The mole ratio of epoxy equivalents to amine equivalents in the adduct ranges from about 2/1 to 10/1.

摘要： Polyurethane foams employing vinyl polymer polyols made by polymerizing in situ via a free-radical mechanism one or more vinyl monomers in an epoxy resin-modified polyol are described. Preferably, styrene and acrylonitrile are copolymerized in a polyol made by adding epoxy resin to the alkoxylation of a polyol initiator having 3 to 4 hydroxyl groups. The vinyl polymer polyols of this invention give flexible polyurethane foams with greater load-bearing properties.

摘要： Novel modified polyether polyols made by first optionally alkoxylating, subsequent reaction with epoxy resins and final alkoxylation of mixtures of initiators is described. The initiator mixture is made up of about 60 to 90 wt. % of a partially alkoxylated trifunctional initiator and 10 to 40 wt. % of a secondary partially alkoxylated initiator having an active hydrogen functionality of from 4 to 8. Preferably, the alkylene oxide component is a blend of ethylene oxide and propylene oxide, and the resulting modified polyol molecules have 0.25 to 2.5 wt. % internally located epoxy resin. Flexible polyurethane foams made from these polyether polyols have improved load bearing properties as compared with those made from prior art polyols.

摘要： Methods and apparatus for eliminating or reducing a surface skin when producing a flexible polyurethane foam slab are disclosed. The top surface of the chemically reactive polyurethane foaming mixture is heated during and/or after the foaming mixture expands. The heating preferably is conducted so as to prevent a significant temperature gradient from forming between the internal temperature of the foaming mixture and the top surface of that mixture. Preferably, heat is applied so as to heat from the top surface of the foaming mixture in an escalating fashion to higher temperatures as the foam is conveyed along a conveying path away from the foaming mixture dispensing device.

摘要： Combinations of gelatinous elastomer and polyurethane foam may be made by introducing a plasticized A-B-A triblock copolymer resin and/or an A-B diblock copolymer resin into a mixture of polyurethane foam forming components including a polyol and an isocyanate. The plasticized copolymer resin is polymerized to form the gelatinous elastomer in-situ while simultaneously polymerizing the polyol and the isocyanate to form polyurethane foam. The polyurethane reaction is exothermic and can generate sufficient temperature to melt the styrene-portion of the A-B-A triblock copolymer resin thereby extending the crosslinking and in some cases integrating the A-B-A triblock copolymer within the polyurethane polymer matrix. The combination has a marbled appearance. The gel component has higher heat capacity than polyurethane foam and thus has good thermal conductivity and acts as a heat sink. Another advantage of in situ gel-foam is that the gel component provides higher support factors compared to the base foam alone.

摘要： The alkylene oxide adduct of bis(aminoethyl)ether may be reacted with formaldehyde in the presence of hydrogen and a hydrogenation-dehydration catalyst to produce compounds of the formula ##STR1## where R is hydrogen or lower alkyl of 1 to 4 carbon atoms and R" is methyl or ##STR2## where R is as above. Monocarboxylic acid salts of these compounds show unexpectedly high efficiency as polyurethane catalysts. Smaller amounts of this amine are required to produce foams having the same reaction profile as foams made with prior art amine salt catalysts.
