Abstract
An abrasive article includes a polymer matrix and abrasive grains dispersed in the polymer matrix, wherein the abrasive article has a void volume of at least 50%. The polymer matrix is polymerized from a monomer including at least one double bond.
Claims20
A method of forming an abrasive article, the method comprising:
- combining polymeric precursors including a monomer having at least one double bond, and abrasive grains to form a first liquid component;
- forming an emulsion from the first liquid component and a second liquid component, the second liquid component substantially immiscible with the first liquid component;
- and
- curing the polymeric precursors of the first liquid component, thereby forming a polymer matrix polymerized from the monomer.
