  公开（公告）日：1989-08-30

  Blends of 90-99 mol % of a polyhydroxyalkane containing 2-6 carbons and 2-3 hydroxyl groups and 1-10 mol % of an aromatic diamine having a pKb value greater than 11.3 are useful as chain extenders for polyurethanes derived from diphenylmethanediisocyanate (MDI) prepoly­mers. Their use overcomes the sensitivity to stoichio­metry common to MDI prepolymer/polyhydroxyalkane systems and leads to the formation of cast elastomers having better green strength and a shorter demold time. The preferred blends are blends of 1,4-butanediol and di(alkylthio)toluenediamines.

  90-99 摩尔%的含 2-6 个碳原子和 2-3 个羟基的聚羟基烷烃与 1-10 摩尔%的 pKb 值大于 11.3 的芳香族二胺的混合物可用作二苯基甲烷二异氰酸酯（MDI）预聚物衍生聚氨酯的扩链剂。它们的使用克服了 MDI 预聚物/聚羟基烷烃体系常见的对化学计量的敏感性，可形成具有更好的生坯强度和更短的脱模时间的浇注弹性体。首选的混合物是 1,4-丁二醇和二(烷硫基)甲苯二胺的混合物。
