摘要： 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.
