ABSTRACT:
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 hydroxyaromatic-aldehyde resole resin is prepared without ammonia or a primary amine and the composition does not contain a triazone or a substituted triazone compound. 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.
