Described is a composition comprising one or more active ingredients coated, dispersed, or dissolved with a mucoadhesive polymer. Although subject to multiple uses, the composition, in some embodiments, is usable for treating rhinosinusitis.
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.
Polymeric flame retardants comprise halognenated aromatic compounds having acylamino functional groups which are chemically bonded to cyclic imide-containing or imide-forming polymers or copolymers. The polymeric flame retardants are prepared by the reaction of halogenated aromatics containing a reactive hydroazido group with some or all of the anhydride groups of an cyclic alpha, beta-unsaturated dicarboxylic acid anhydride polymer or copolymer to form pendant halogenated-aromatic-substituted imide or amic acid groups. In addition, polymeric flame retardants are used to render thermoplastic resin less flammable under conditions which promote combustion. Novel flame retardant hydrazides are disclosed.
