Abstract

A crosslinking agent suitable for acrylic rubbers, particularly for acrylic rubbers containing units of a cyanoacetic acid comonomer or a malonic acid comonomer for imparting a crosslinkability, which comprises a reaction product of formaldehyde or a polymerized formaldehyde with urea or thiourea in the presence of an acidic catalyst.
