Disclosed is a class of poly(aminoaromatic) compounds (I) obtained by capping polymeric polyols or polythiols with aromatic amine groups wherein the latter groups are linked by -O- or -S- to the polyol (polythiol) residues. Also disclosed are the precursor poly(nitroaromatic) compounds (II) and process therefor from which the compounds (I) are derived.
The polyamines are characterized by amine reactivities in respect of isocyanate polyaddition reactions which allows for polymer reaction rates that are intermediate of prior art related polyamine compounds.
Accordingly, the compounds (I) find their prime utility in the formation of synthetic resins containing polyurea linkages.
公开了一类聚(氨基芳香族)化合物 (I),该化合物通过用芳香族胺基团封端聚合多元醇或聚硫醇而获得,其中芳香族胺基团通过 -O- 或 -S- 连接到多元醇(聚硫醇)残基上。 还公开了前体聚(硝基芳香族)化合物 (II) 及其工艺,化合物 (I) 就是从这种工艺中衍生出来的。 多胺的特点是在异氰酸酯加成反应中具有胺反应活性,从而使聚合物反应速率介于现有技术相关多胺化合物之间。 因此,化合物 (I) 在形成含有聚脲连接的合成树脂方面具有重要用途。
