Abstract
An abrasive article is provided that includes at least one binder system formed from a polymeric additive and a thermosetting resin. The polymeric additive includes a polymeric backbone having substituents attached thereto, wherein the substituents include at least one urethane linked nitrogen bonded side chain having about 5 carbon atoms or more and a terminal methyl group and at least one oxygen linked water solubilizing group. An abrasive article that includes the binder system exhibits an increase of workpiece surface abraded in a Woodsanding Normal Force Test as compared to an abrasive article including a binder system formed from a composition containing substantially no polymeric additive.
