ABSTRACT:
Coated abrasive articles have a tie layer that is preparable by at least partially polymerizing an isotropic polymerizable composition comprising a polyfunctional aziridine, an acidic free-radically polymerizable monomer, and an oligomer having at least two pendant free-radically polymerizable groups, wherein homopolymerization of the oligomer results in a polymer having a glass transition temperature of less than 50 degrees Celsius.
