Abstract: An NO abatement process wherein an NO-containing fluid is contacted with a polymeric cobalt(II) dioxygen diamine complex. The aqueous solution is recovered, purified by membrane separation to remove low molecular weight reaction products, optionally electrolytically regenerated, and recycled for the NO-containing gas contact. The cobalt(II) is complexed with an amine-containing polymer such as polyethyleneimine free of acidic, e.g. carboxylate, chelating groups.
Abstract: Novel interpolymers of ethylene, omega-alkenyl pyridines, such as vinylpyridines, and optionally, another monomer interpolymerizable therewith. The interpolymer is prepared by free-radical initiation in a reactor operated at a pressure of from about 70 MPa to about 350 MPa and a temperature of from about 50.degree. C. to about 300.degree. C. The interpolymers are primarily useful as adhesives.

Abstract: An insect-resistant composition containing at least about 75 percent by weight of a polyethylene, e.g. LDPE, HDPE, or LLDPE, at least about 5 percent by weight, up to an amount approaching about 25 percent by weight of a compatability additive selected from chlorinated polyethylene and ethylene-n-butyl acrylate copolymer, and an insecticidally effective amount, up to about 8 weight percent, of an insecticide, e.g. halopyridyl phosphates. Optionally, the compatibility additive may include carbon black in an amount of about 0.5-7.5 percent by weight of the composition. The composition has utility in being formed into useful articles, especially in wire and cable applications, which are insect resistant substantially for the useful life of the articles.
