    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.

    Abstract: PROBLEM TO BE SOLVED: To provide a method by which a rigid polyurethane foam excellent in dimensional stability at low temperatures can be produced. SOLUTION: A tertiary amino-alcohol represented by formula I [R1 denotes a 1-24C straight-chain or branched alkyl group, etc.; (m) denotes a number of 3-50 on the weight average; R2 denotes a 2-20C straight-chain or branched alkylene group, etc.] is used as at least a part of an active hydrogen-containing compound and a reaction is carried out in the presence of a compound represented by formula II R3 (X)n [R3 is an (n)-valent hydrocarbon group; X denotes the same or different anionic eliminable group; (n) is an integer of >=2] when reacting an isocyanate compound with the active hydrogen-containing compound and producing a rigid polyurethane resin.

    Abstract: PURPOSE:To obtain the subject foam having excellent physical properties even when a metallic mold is heated at a high temperature by reacting a polyol component containing a specific tertiary amino-alcohol with a polyisocyanate component in the presence of water. CONSTITUTION:The objective low-density polyurethane foam is obtained by reacting (A) a polyisocyanate component such as polylene diisocyanate with (B) a polyol component containing a tertiary amino-alcohol expressed by the formula [R1 is 2-24C alkylene, aryl or aralkyl; the average polymerization degree n is a positive number; (q) is a positive number 11; R2 is 1-24C alkyl, aryl or aralkyl; the average polymerization degree n is a positive number of 1-50} as an essential component in the presence of water in an amount of 2-8 pts.wt. based on 100 pts.wt. total amount of the component (B).

    Abstract: PURPOSE:To improve the mold-filling properties of a polyurethane by mixing a polyisocyanate component with a polyol component consisting partly or wholly of at least one specific t-amino alcohol. CONSTITUTION:A polyisocyanate or a mixture of two or more polyisocyanates is mixed with a polyol component consisting of 99-60wt.% generally used polyol and 1-40wt.% t-amino alcohol of formula I and/or III [wherein R1 and R3 are each 2-24C linear or branched alkylene, alicyclic alkylene, cycloalkylene, arylene, aralkylene, or a group of formula II (wherein (p) is 0 or a positive integer; and (q) is a positive integer); R2 and R4 are each 1-24C linear or branched alkyl, aryl, or aralkyl; and (n) is a degree of polymn. being 1-4] in a molar ratio of NCO/OH of 1.0-1.2 and with other additives to give the objective polyurethane having improved mold-filling properties.

    Abstract: PURPOSE:To obtain a catalyst which is odorless, can be easily handled and can give a polyurethane having good air permeability and compression set by using a specified compound having a specified dimethylamino structure. CONSTITUTION:A catalyst for producing a polyurethane comprising a compound of the formula (wherein n is 1-3; R1 is H or CH3; and R2 is an isocyanate residue). Although a morpholine catalyst such as N-methylmorpholine is conventionally used as a catalyst for producing a polyurethane, it is difficult to work because of its low b.p. and strong irritating odor. Further, the obtained polyurethane product emits a strong irritating odor. Although an organotin compound which is a commonly used organometallic compound is lowly odorous, it is a resinification catalyst having a strong catalytic activity and therefore cannot be used alone. Because the compound of the above formula which is a reaction product of dimethylaminopolyalkanolamine with an isocyanate has a moderate catalystic activity, is odorless and gives a foam which has excellent properties, it is suitable as a catalyst for producing polyurethane.
