    • A one-component-type composition for a polyurethane elastomer, comprising as a main component a polyurethane precursor containing a polyisocyanate component, and a compound having active hydrogen groups. The polyisocyanate component contains a polyisocyanate having at least a urethodione group (particularly urethodione and isocyanurate groups), and the compound (polyol or the like) having active hydrogen groups contains at least two active hydrogen groups in its molecule and has a molecular weight of 18 to 20000. The polyurethane precursor is obtained by reacting the polyisocyanate component and the compound having active hydrogen groups under the condition that the equivalent ratio of the active hydrogen group in the compound having active hydrogen groups to the isocyanate group in the polyisocyanate component exceeds 1.0. The equivalent ratio of the urethodione group to the active hydrogen group in the polyurethane precursor is from 0.25 to 1.0. The one-component-type composition for a polyurethane elastomer has storage stability comparable to that of thermoplastic elastomers, can be handled with ease, and does not pollute working environment. The composition is useful for preparaing elastomers which have physical properties equal to those of two-component-type elastomers.
    • 用于聚氨酯弹性体的单组分型组合物,其包含作为主要组分的含有多异氰酸酯组分的聚氨酯前体和具有活性氢基团的化合物。 多异氰酸酯成分含有至少具有脲基(特别是脲基和异氰脲酸酯基)的多异氰酸酯,具有活性氢基的化合物(多元醇等)在其分子中含有至少两个活性氢基,分子量为18 聚氨酯前体是通过使多异氰酸酯组分和具有活性氢基团的化合物在多异氰酸酯组分中的具有活性氢基团的化合物中的活性氢基团与异氰酸酯基团的当量比超过1.0的条件下反应而获得的。 脲基组与聚氨酯前体中活性氢基团的当量比为0.25〜1.0。 用于聚氨酯弹性体的单组分型组合物具有与热塑性弹性体相当的储存稳定性,可以容易地处理,并且不会污染工作环境。 该组合物可用于制备具有与双组分型弹性体相同的物理性质的弹性体。
