Discrete particles that include a polymeric material and articles formed therefrom

摘要

The present invention provides discrete particles and methods of preparing the discrete particles. The discrete particles include a plurality of abrasive grits and a polymeric material that includes a reaction product of components including (a) an epoxy-functional material, (b) at least one of a cyclic anhydride or a diacid derived therefrom, and optionally (c) a polyfunctional (meth)acrylate. The invention also provides articles made from the discrete particles and methods of making such articles. Preferably, the articles are abrasive articles.
