Abstract: PROBLEM TO BE SOLVED: To provide an antistatic shoe sole having an excellent hydrolysis resistance, and excellent strength and appropriate conductivity as a whole, and antistatic shoes using the same. SOLUTION: The antistatic shoe sole having a molding density of 0.9 g/cm or more is formed by reacting a compound having two or more active hydrogen atoms per molecule and containing polyetherpolyol as the main component thereof with a polyisocyanate compound under the presence of an electrically conductive agent and a catalyst and subjecting the product to pressure work. The antistatic shoes comprise the antistatic shoe soles.

Abstract: PROBLEM TO BE SOLVED: To obtain a cross-linked resin excellent in properties such as strengths and stability against various solvents by cross-linking a polymer having tert. amino groups in the molecular skeleton and having hydroxyl groups at both molecular terminals with a hydrocarbon having an anionic leaving group in the molecule. SOLUTION: A polymer of a compound represented by formula I (wherein R1 is a 1-24C alkyl or an aralkyl; m is 3-50 on the weight average; R2 is a 2-20C alkylene, an alicyclic alkylene, an aralkylene or the like) is cross-linked with a compound represented by the formula: R3 (-X)n (wherein R3 is an n-valent hydrocarbon group; X is an anionic leaving group; and n is an integer of 2 or greater) (e.g. 1,6-dibromohexane). The tert. alcohol is obtained by for example reacting a dihydric alcohol with a prim. amine. The dihydric alcohol is exemplified by 1,3-butanediol, and the prim. amine is exemplified by methylamine.

Abstract: PROBLEM TO BE SOLVED: To obtain a polyurethane foam having yellowing resistance and showing unimpaired resin strength in mold release and excellent moldability even when the amount of the water-containing blowing agent is increased by reacting an isocyanato-reactive compound with a polyisocyanate in the presence of a specified catalyst. SOLUTION: In reacting a compound having two or more isocyanato-reactive hydrogen atoms and having a molecular weight of 400-10,000 with a polyisocyanate in the presence of a catalyst and a blowing agent, 0.1-3.0 pts. wt. compound (e.g. a compound of formula II or III) represented by formula I (wherein R1 and R2 are each H or a 1-4 C alkyl) is used per 100 pts.wt. isocyanato-reactive compound to produce a polyurethane foam having density of 0.20-0.40g/cm and a tensile strength of 20kg/cm or above. The use of the above catalyst makes it possible to obtain a polyurethane foam having unimpaired strength by virtue of its excellent gelation reactivity in mold release and excellent moldability, having yellowing resistance, and being suited for especially soles even when the amount of the water as the blowing agent is increased to lower the density of the foam.
