    摘要: The reaction products of polyallylnadic anhydride and various polyamines are latent hardeners for use in epoxy resins having more than one 1,2-epoxy groups per molecule. Mixtures of these products and epoxy resins are stable at room temperature for extended periods, yet cure quickly at elevated temperatures to yield products with high glass transition temperatures.
