    Abstract: A process for producing a polyurethane foam which comprises reacting a polyol ingredient with an isocyanate ingredient in the presence of a catalyst comprising a compound represented by formula (I), (wherein p is an integer of 4 to 8) and a compound having a primary amino group and a tertiary amino group in the molecule, a foaming agent, and a foam stabilizer. The polyurethane foam obtained by the process is suitable for use as a building material, a heat insulation material for electrical refrigerators, cold storages, bathtubs, etc., a material for interior automotive trims, etc.

    Abstract: Microcellular polyurethane elastomer shoe sole components having exceptional physical properties may be prepared from isocyanate-terminated prepolymers derived from polyoxypropylene diols having a molecular weight of from about 2000 Da to 8000 Da, an unsaturation less than about 0.02 meq/g, and a random oxyethylene content of from about 5 to about 15 weight percent. The shoe sole components exhibit high tensile strength, elongation, resilience, and in addition have excellent tear strength, particularly 90° angle tear.

    Abstract: A catalyst for polyurethane production which comprises a dialkylaminoalkyl alcohol represented by the formula (I): R R N-X-OH (wherein R and R each independently represents C1-4 alkyl and X represents C4-8 branched alkylene); a process for producing a polyurethane which comprises reacting a polyol ingredient with an isocyanate ingredient in the presence of the catalyst; and a process for producing a polyurethane foam which comprises reacting a polyol ingredient with an isocyanate ingredient in the presence of the catalyst, a polyurethane production catalyst which comprises a compound having a primary amino group and a tertiary amino group in the molecule, and a foaming agent. The polyurethane is usable as a heat insulator for building materials, electric refrigerators, cold storehouses, bathtubs, etc., an interior automotive material, a cushioning material for furniture and bedding, various sealing materials, and the like.

    Abstract: A PROCESS FOR PREPARING A POLYURETHANE FOAM COMPRISING REACTING AN ISOCYANATE COMPOSITION COMPRISING A POLYESTER-POLYOL PREPARED BY POLYCONDENSATION OF A POLYBASIC ACID COMPONENT COMPRISING AN AROMATIC POLYBASIC ACID AND AN ALIPHATIC BASIC ACID, WHEREIN THE MOLAR RATIO OF THE AROMATIC POLYBASIC ACID TO THE ALIPHATIC BASIC ACID IS 0.05 TO 0.4, AND A POLYHYDRIC ALCOHOL COMPONENT, AND AN ISOCYANATE-TERMINATED PREPOLYMER PREPARED BY REACTING A POLYETHER-POLYOL HAVING AN AVERAGE NUMBER OF FUNCTIONAL HYDROXYL GROUPS OF 2 TO 6 AND A NUMBER-AVERAGE MOLECULAR WEIGHT OF 1,500 TO 20,000 WITH AN ORGANIC POLYISOCYANATE (COMPONENT A); WITH A POLYOL COMPONENT COMPRISING A POLYESTER-POLYOL OR POLYETHER-POLYOL, A CHAIN EXTENDER, A BLOWING AGENT, AND A URETHANE PROMOTING CATALYST (COMPONENT B). ACCORDING TO THE PROCESS OF THE PRESENT INVENTION, A PLOYURETHANE FOAM HAVING EXCELLENT FINAL PHYSICAL PROPERTIES SUCH AS TENSILE STRENGTH, WHICH CAN BE SUITABLY USED PARTICULARLY AS A POLYURETHANE FOAM FOR SHOE SOLES, CAN BE OBTAINED WITHOUT THE GENERATION OF PINHOLES OR SHRINKAGES ON THE SURFACE OF THE FORMED ARTICLES.
