摘要:
A polyurea elastomer comprising the reaction product of an organic polyisocyanate, an aromatic amine-terminated chain extender, an isocyanate-reactive amine having a molecular weight of at least 200 and at least two isocyanate-reactive groups at least 50 % of which are aliphatically bound primary and/or secondary amino groups and an aldehyde or ketone in an amount equivalent to at least 5 % of the aliphatic amino group content of the isocyanate-reactive amine.
