    摘要： A reaction system for use in making a reaction injection moulded elastomer, said system comprising the following components :

    (A) a polyisocyanate composition comprising a reaction product of a stoichiometric excess of an organic polyisocyanate and :

    (i) a polymeric polyol having an average nominal hydroxyl functionality greater than 2 and an average hydroxyl equivalent weight of from about 500 to about 5000, and
    (ii) a polymeric polyamine having an average nominal primary and/or secondary amino functionality of from about 2 to about 3 and an average amine equivalent weight of from about 500 to about 5000, the polyol and the polyamine having glass transition temperatures below room temperature.

    (B) an isocyanate-reactive composition comprising at least one imino-functional compound.
