    • Provided are a urethane resin solution to provide a urethane resin having a low tensile elasticity, a low elastic modulus under low temperatures, good elastic recovery, excellent heat resistance and excellent adhesion, a production method of the solution and a production method of the urethane resin. An isocyanate group-terminated prepolymer is synthesized by reacting a polyisocyanate compound with a polyetherester diol having a molecular weight of from 800 to 4,000, which is obtained by a ring-opening polymerization of a mixture of an alkylene oxide and a lactone monomer using a polyoxy tetramethylene diol having a molecular weight of from 500 to 2,500 as an initiator and using a composite metal cyanide complex catalyst if necessary, and the resulting prepolymer is reacted with a chain extender, for example, comprised of a low molecular weight diamine and/or a low molecular weight diol, in an organic solvent. The urethane resin solution obtained is molded into a predetermined shape, or a substrate is coated or impregnated with the urethane resin solution and thereafter the organic solvent is removed to obtain a urethane resin.
    • 提供一种聚氨酯树脂溶液,其提供具有低拉伸弹性,低温下的低弹性模量,良好的弹性恢复性,优异的耐热性和优异的粘合性的聚氨酯树脂,该溶液的制备方法和聚氨酯树脂的制备方法 。 通过使多异氰酸酯化合物与分子量为800〜4000的聚醚酯二醇反应来合成异氰酸酯基封端的预聚物,其通过使用聚氧化烯的环氧烷和内酯单体的混合物的开环聚合获得 分子量为500〜2,500的四亚甲基二醇作为引发剂,如果需要使用复合金属氰化物配合物催化剂,所得预聚物与扩链剂例如由低分子量二胺和/或 低分子量二醇,在有机溶剂中。 将得到的聚氨酯树脂溶液成型为规定形状,或者将基材涂布或浸渍聚氨酯树脂溶液,然后除去有机溶剂,得到聚氨酯树脂。
