Abstract: A solventless, fast-setting anaerobic adhesive composition comprises two monomer parts which are adapted to be copolymerized anaerobically at ambient temperature between opposing surfaces to form a high-strength bond thereto. One part comprises a multifunctional acrylate monomer and the other an N-vinylamide monomer. The formulation also includes a redox system consisting of oxidizing and reducing agent components for initiating polymerization between said monomers. The oxidizing agent of the redox system may be present in either one of said parts, preferably with the multifunctional acrylate. The reducing agent is present in the other part, usually the N-vinylamide. Upon anaerobic admixing of the respective parts of the composition at ambient temperature, the oxidizing and reducing agents react to generate free radicals which initiates copolymerization of the monomers to form the desired high-strength adhesive bond to said surfaces.

Abstract: The invention provides broad spectrum herbicidal diacylimide compositions which include compounds having the formula: ##STR1## where R and R' are selected from alkyl, alkenyl, haloalkyl and haloalkenyl having from 1-5 carbon atoms, being the same or different groups.The compositions of this invention show excellent agricultural herbicidal activity, particularly against foxtail millet, Japanese millet, crabgrass and pigweed, and aquatic herbicidal activity against lower and higher submerged aquatic plants.The diacylimide compounds generally are prepared by reacting a suitable amide with an acyl halide. The acyl halide precursor may be prepared, if necessary, from the corresponding acid by reaction with a suitable halogenating agent, such as thionyl chloride. Similarly, a given amide may be readily prepared, for example, from the corresponding acyl halide by reaction with ammonia.
