Abstract
A curable composition comprises: blocked polyisocyanate, curative, and a crosslinked copolymer of monomers comprising at least one free-radically polymerizable carboxylic acid and at least one of an alkyl or alkaryl (meth)acrylate. Methods of making the curable compositions and their use in the manufacture of abrasive articles are also disclosed.

An abrasive article comprising abrasive particles and a polymerized reaction product of a curable composition comprising:
- blocked polyisocyanate;
- curative;
- and
- a crosslinked copolymer of monomers comprising at least one free-radically polymerizable carboxylic acid and at least one of an alkyl or alkaryl (meth)acrylate, wherein at least one of the alkyl or alkaryl (meth)acrylate has from 11 carbon atoms to 34 carbon atoms, and wherein the amount of crosslinked copolymer is in a range of from 1 percent by weight to 20 percent by weight, based on the total weight of the curable composition.

A method of abrading a workpiece comprising:
- providing an abrasive article comprising:
- abrasive particles and a polymerized reaction product of components comprising:
- blocked polyisocyanate;
- curative;
- and
- a crosslinked copolymer of monomers comprising at least one free-radically polymerizable carboxylic acid and at least one of an alkyl or alkaryl (meth)acrylate, wherein at least one of the alkyl or alkaryl (meth)acrylate has from 11 carbon atoms to 34 carbon atoms, and wherein the amount of crosslinked copolymer is in a range of from 1 percent by weight to 20 percent by weight, based on the total weight of the curable composition;
- and
- frictionally contacting at least one abrasive particle with at least a portion of the surface of the workpiece;
- and
- moving at least one of the at least one abrasive particle or the workpiece relative to the other to abrade at least a portion of the surface.
