Title: Process for curing acrylic polymers

Abstract: Acrylic polymers are typically difficult to cure unless they contain specific curing sites, such as carbon-carbon double bonds. This invention offers a technique to rapidly cure acrylic polymers containing nitrile groups that do not possess typical curing sites, such as carbon-carbon double bonds. By utilizing the process of this invention, heat resistant thermoplastic vulcanizates with high-resistance to solvents can easily be prepared. The present invention more specifically discloses a process for curing an acrylic polymer which comprises distributing an aromatic compound having at least two nitrile oxide groups bonded thereto throughout the acrylic polymer, wherein the acrylic polymer contains nitrile groups, and wherein a bulky group is in at least one ortho position to the nitrile oxide group and wherein the bulky group is a moiety which is larger than a hydrogen atom.
