    • A thermoplastic polyurethane composition comprising a thermoplastic polyurethane and a tin compound in an amount of 0.3-15 ppm (in terms of tin atom) based on the polyurethane. The composition has a retention of the long-chain hard segment of the polyurethane of 85 % or above when melt treated at 220 °C for 60 minutes. Further it has a retention of the logarithmic viscosity of 85 % or above when melt treated at 220 °C for 6 minutes, melt extruded and left to stand at 20 °C and 60 % R.H. for 24 hours. The composition is so excellent in moldability that it can provide moldings excellent in various properties such as tenacity and elongation, thermal resistance, compression set and hydrolysis resistance, thus being useful as the material of various moldings. Further it is so excellent in spinnability that it can provide fibers excellent in various properties such as thermal resistance, hydrolysis resistance and unwindability, thus being useful also as the material of elastic fibers.
    • 一种热塑性聚氨酯组合物,其包含基于聚氨酯的0.3-15ppm(以锡原子计)的热塑性聚氨酯和锡化合物。 当在220℃下熔融处理60分钟时,该组合物具有85%或更高的聚氨酯的长链硬链段的保留。 此外,当在220℃下熔融处理6分钟时,其对数粘度保持在85%以上,熔融挤出,并在20℃和60%R.H.下静置24小时。 该组合物的成型性优异,能够提供各种性能如强度和伸长率,耐热性,压缩变形和耐水解性优异的模制品,因此可用作各种模制品的材料。 此外,其可纺性如此优异,可以提供各种性能如耐热性,耐水解性和展开性优异的纤维,因此也可用作弹性纤维的材料。

    • A powder coating composition comprises 100 weight parts of the total of a polyester resin having a hydroxyl value in the range from 20 to 100 KOH mg/g and a blocked polyisocyanate compound, 0.01 to 3 weight parts of an organotin compound and 0.01 to 10 weight parts of a carboxylic acid compound having an acid value of 1000 KOH mg/g or less which can form a complex compound by reaction with the organotin compound. The amount of the polyester resin is in the range from 95 to 50 weight % and the amount of the blocked polyisocyanate compound is in the range from 5 to 50 weight % respectively based on the total of the polyester resin and the blocked polyisocyanate compound. A precoat steel plate is prepared by coating the powder coating composition described above on a steel plate by a electrostatic powder coating method to form a coating layer having a thickness in the range from 20 to 120 µm and curing the coating composition by baking at a temperature in the range from 190 to 300°C for a time in the range from 20 seconds to 10 minutes. The powder coating composition can be cured without formation of blisters and pin holes under a desired condition by controlling the rate of the curing reaction.
