A composition is disclosed, which comprises a hydroxyaromatic-aldehyde resole resin comprising an aldehyde and a hydroxyaromatic compound, modified with a urea-aldehyde condensate. The composition has improved premix stability, improved cure efficiency, comparable tensile strength, and lower volatiles than the hydroxyaromatic-aldehyde resole resin unmodified with a urea-aldehyde condensate. Also disclosed are articles prepared therefrom.
                            本发明揭示了一种组合物,其包括一种含有醛和羟基芳香化合物的羟基芳香醛
树脂,该
树脂经过
尿素-醛缩合物的改性。该组合物具有改善的预混稳定性,改善的固化效率,可比的拉伸强度以及比未经
尿素-醛缩合物改性的羟基芳香醛
树脂更低的挥发物。同时,本发明还揭示了由该组合物制备的制品。
