摘要： PURPOSE:To produce the titled polyurethane capable of forming a molding excellent in light resistance, NOX gas resistance, flexibility, etc. by reacting a polymer diol with an alicyclic diisocyanate compound and isophthalic acid dihydrazide in a specified manner. CONSTITUTION:A hydroxyl group-terminated polymer diol (A) of an average MW of 1,000-3,500 (e.g., polycaprolactone glycol) is reacted with an alicyclic diisocyanate compound (B) (e.g., dicyclohexylmethane 4,4-diisocyanate) at a molar ratio of 1:1.2-1.9 until the terminal hydroxyl groups in component A are substantially completely eliminated. To the obtained isocyanato group-terminated prepolymer, component B in an amount to provide a molar ratio of component A to component B in the produced polyurethane of 1:2.5-6 and isophthalic acid dihydrazide are added, and the resulting mixture is reacted to obtain a polyurethane.

摘要： PURPOSE:To produce the titled polyurethane excellent in light, heat and hydrolysis resistances, by using a specified isocyanato-terminated prepolymer or a specified hydroxyl-terminated prepolymer. CONSTITUTION:A polyol obtained by the ring opening copolymerization of beta- methyl-delta-valerolactone with a low-molecular polyhydric alcohol (e.g., ethylene glycol) is reacted with an excess or insufficient amount of a polyisocyanate compound to obtain an isocyanato-terminated or hydroxyl-terminated prepolymer having a group of the formula and an average MW of 300-6,000. This prepolymer is mixed with a polyisocyanate (e.g., diphenylmethane-4,4'-diisocyanate) or an active hydrogen-containing polyvalent compound (e.g., ethylene glycol), and the mixture is cured after defoaming and molded at room temperature-130 deg.C.

摘要： PURPOSE:To produce a polyurethane having no tendency toward crystallization and excellent hydrolysis resistance, weather resistance, mechanical properties, oil resistance, abrasion resistance, and low-temperature resistance, by reacting a specified polyol with a polyisocyanate. CONSTITUTION:A polyester-polyol of an average MW of 300-10,000 is obtained by polycondensing a mixture of 20-100wt% 3-methylpentanedioic acid and 80- 0wt% dicarboxylic acid (e.g., adipic acid) with a molar excess of a glycol (e.g., ethylene glycol). This polyester-polyol is mixed with an active hydrogen-containing low-MW compound (e.g., ethylene glycol) and, after preheating the mixture to 40-100 deg.C, a polyisocyanate (e.g., 2,4-tolylene diisocyanate) is added in such an amount that the ratio of the number of the active hydrogen atoms of these compounds to that of the NCO groups is 1:1, and the resulting mixture is agitated vigorously for a short time and allowed to stand at 50-150 deg.C.
