摘要：
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. The composition is especially useful in the production of elastomers by the RIM process.
