摘要：
Abrasive articles and methods of making and using same are presented, the abrasive articles having a peripheral surface adapted to contact and abrade a workpiece. The abrasive articles comprise abrasives particles and a grinding aid composition positioned at an effective location in reference to the abrasive particles, the grinding aid composition comprising:a) a cured grinding aid binder comprising a blend of a thermoplastic resin and a thermoset resin, the thermoplastic resin and thermoset resin being present at an effective weight ratio; andb) an effective amount of a grinding aid dispersed in the grinding aid binder.
