Abstract:
1. A method of making a coated abrasive article comprising: disposing a first polymerizable composition on at least a portion a backing, the first polymerizable composition comprising an isotropic composition comprising at least one polyfunctional aziridine; disposing a second polymerizable composition comprising at least one acidic free-radically polymerizable monomer and at least one oligomer having at least two pendant free-radically polymerizable groups on at least a portion of the first polymerizable composition, wherein homopolymerization of the oligomer results in a polymer having a glass transition temperature of less than 50 degrees Celsius; at least partially polymerizing the first and second polymerizable compositions to form a composite tie layer; disposing a polymerizable make resin precursor on the composite tie layer; embedding abrasive particles in the make resin precursor; at least partially polymerizing the make resin precursor; disposing a polymerizable size resin precursor on the at least partially polymerized make resin precursor; and at least partially polymerizing the size resin precursor.
