Phenolic resin composition comprising polymerized ionic groups, abrasive articles and methods

Abstract

A phenolic resin composition is described comprising at least 50 wt.-% of phenolic resin; first polymerized units comprising a cationic group; and second polymerized units comprising an anionic group. The cationic groups are ionically bonded to the anionic groups. The ionic bonding of the cationic group and anionic group of the polymerized units can provide certain complex viscosity and/or tan delta properties. In some embodiments, the phenolic resin composition has a complex viscosity at 65C of at least 50 Pascal(seconds) and/or has a tan delta at 65C ranging from 0.5 to 2.5. Abrasive articles and methods of making an abrasive article are also described.
