Abstract: Novel reverse osmosis membranes and a method for preparing such membranes are described. A substrate can be coated with a first compound bearing a plurality of onium groups and a second compound bearing a plurality of nucleophilic groups. The resulting coating cures readily upon exposure to actinic radiation.

Abstract: Novel photocurable, adherent coating compositions and a method for preparing such compositions are described. A substrate can be coated with a first compound bearing a plurality of onium groups and a second compound bearing a plurality of nucleophilic groups. The resulting coating cures readily upon exposure to actinic radiation. These compositions can be used in preparation of photoresists, composite membranes, and modifying surfaces either for accepting adhesives or releasing oily soil.

Abstract: The invention discloses a method of treating swine dysentery by the administration of an animal feed composition containing an effective amount of an alkoxysilane compound such as 3-(triethoxysilyl)propyloctadecyldimethyl ammonium chloride.

Abstract: 3,7-Substituted phenoxiodinin-5-ium compounds are effective against a variety of aerobic and anaerobic bacteria as well as fungi. The compounds of this invention may be prepared by the direct iodination of a suitably substituted diphenyl ether with iodosyl sulfate in concentrated sulfuric acid. The resulting bisulfate anion may be exchanged with a desired anion by standard metathetic processes.

Abstract: Process and composition for dental hygiene in which the teeth of animals are contacted with a long-chain alkyl thiouronium phosphonate.

Abstract: New and useful aliphatic multifunctional cyanate compounds are prepared by the reaction of thallium(I) salts of polyols with cyanogen chloride. The compounds are useful for common reactions known for multifunctional cyanates including rearrangement into the corresponding isocyanate and then formation of polymers or use as cross-linking agents.

Abstract: Aliphatic compounds containing isocyanato and hydroxyl functionality are formed by reacting the alkali metal salt of a dihydroxy-substituted aliphatic compound with cyanogen halide producing a monomeric product containing both cyanato and hydroxyl functionality that subsequently rearranges to produce the desired compounds.

Abstract: New and useful halogenated alkenyl isocyanurate compounds of the formula ##STR1## wherein R.sub.1 and R.sub.2 are specified substituents are formed by reacting a halogenated isocyanurate compound with a di- or polyolefin.

Abstract: A process is disclosed for the preparation of alkyl cyanates, alkyl isocyanurates, multifunctional alkyl cyanates, and oligomers of multifunctional alkyl isocyanates by reacting cyanogen halide with the corresponding thallium(I) salt of an alkanol at reduced temperatures, optionally in the presence of an inert solvent. Subsequently, warming the resulting product to ambient temperature causes isomerization to the corresponding aliphatic isocyanate and ultimately oligomerization to form trialkyl isocyanurate or oligomers of multifunctional alkyl isocyanates.

Abstract: Halogenated modified isocyanurates of the general formula: ##STR1## wherein R.sub.x is a halogenated alkyl or alkenyl radical; R.sub.1 and R.sub.2 are individually either halogenated alkyl radicals, halogenated alkenyl radicals, or unreactive alkyl or aryl moieties, are formed by the reaction of olefins or halogenated olefins with appropriate halogenated modified isocyanate compounds of the general formula: ##STR2## wherein X is a halogen and R.sub.1 ' and R.sub.2 ' are individually either halogens or unreactive alkyl or aryl moieties, in the presence of a solvent.
