Disclosed herein are methods of preparing an aminimide. An epoxy compound is reacted with a hydrazine compound comprising a trivalent nitrogen, and an anhydride functional material or a cyclic compound containing a carbonyl group and at least one heteroatom alpha to the carbonyl group at a temperature greater than 20o?C to form the aminimide. At least one of the epoxy compound and the anhydride functional material or the cyclic compound is polymeric. Also disclosed herein is an adhesive composition comprising an epoxy compound and a compound comprising at least one aminimide functional group is disclosed. The compound comprising the at least one aminimide functional group is present in an amount from 2-8% by weight based on total weight of the adhesive composition and reacts with the epoxy compound upon activation by an external energy source. The adhesive composition also may comprise an amidine salt.
