The Formulations of the present invention are effective as broad spectrum anti-bacterial agents with efficacy against both Gram-negative and Gram-positive bacteria, as anti-viral agents with efficacy against both enveloped and non-enveloped viruses, anti fungal agents and anti spore forming agents. The present invention includes anti-microbial Formulations that include at least one surfactant, optionally at least one acid, at least one non-cationic anti-microbial agent, and optionally water. The anti-microbial Formulations of the present invention may additionally contain an organic salt. The organic salt may be a salt of the same acid that is used in the Formulation or a salt of a different acid.
Anti-Microbial Composition And Method For Making And Using Same
The present invention generally relates to anti-microbial formulations and methods of their use and production. The formulations of the present invention are effective as broad spectrum anti-bacterial agents with efficacy against both Gram-negative and Gram-positive bacteria, as anti-viral agents with efficacy against both enveloped and non-enveloped viruses, and as anti-fungal agents with efficacy against both vegetative and spore forms of microorganisms and against biofilms. The present invention includes anti-microbial compositions that have at least one surfactant, at least one acid, at least one peroxide (preferably hydrogen peroxide), peracetic acid, and water. The anti-microbial Formulations of the present invention may additionally contain an organic salt. The organic salt may be a salt of the same acid that is used in the Formulation or a salt of a different acid. Methods for production and use of the inventive compositions are disclosed.

Abstract:
A process for encapsulating a wide variety of target materials, including both hydrophilic and hydrophobic materials, employs condensation of two reactive compounds to form shells around core phase particles including target material dispersed in a continuous phase. One of the reactive compounds has at least two active methylene functional groups per molecule, the other being an active methylene-reactive crosslinking agent. Either type of the reactive compounds can be dispersed in the continuous phase, the other being dispersible in the core phase. Applications include controlled release microencapsulation of agriculture chemicals and biocides.

Abstract:
Abrasive articles comprising a cured thermosetting binder and abrasive grains. The binder is prepared with a poly-functional molecule comprising at least two functional groups selected from the group consisting of carboxyl and anhydride, and a crosslinking agent which is selected from the group consisting of a mono(hydroxyalkyl)urea comprising a single urea group, a single hydroxyl group, and at least two carbon atoms disposed between the urea group and the hydroxyl group, and 2-oxazolidone. The abrasive articles comprise bonded, nonwoven or coated abrasive articles.

International Classification:
C08J 300 C08K 320 C08L 7500
US Classification:
524591
Abstract:
A process for preparing aqueous dispersions of polyurethanes comprises dispersing polyurethane prepolymer containing unreacted --NCO functionality in water with moderate agitation at a temperature at or below 65. degree. C. , preferably at or below 38. degree. C. , and more preferably within the range 38. degree. -25. degree. C. ; simultaneously reducing the agitation to a mild rate and maintaining the temperature within the range 38. degree. -85. degree. C. , preferably, 60. degree. -65. degree. C. , until the reaction of --NCO with water levels off; adding an effective amount of a quenching agent to react with sufficient --NCO functionality to reduce the number of available --NCO groups that can react with water so that the evolution of CO. sub. 2 is reduced or eliminated during storage of the polyurethane dispersion; and at any of the previous sequential steps adding an effective amount of a deaerating agent to reduce or eliminate CO. sub. 2 foaming or to liberate any dissolved CO. sub. 2 gas.

Abstract:
A coating or impregnating composition containing an aqueous dispersion of a vinyl addition polymer and a reactive coalescent is provided. The reactive coalescent contains at least one acetoacetate grouping, or an enamine thereof. In one embodiment the reactive coalescent also functions as an emulsion polymer crosslinker.
This invention is concerned with an article comprising a polyolefin substrate and adherent thereto a vinyl addition polymer of monomers comprising at least 5% by weight a primary monomer selected from (a) monomers having the formula ##STR1## wherein X is --O--, --NH-- or --NR. sup. 5 --; R. sup. 1 and R. sup. 7, individually, are H, methyl or ethyl; R. sup. 2 is H or an organic radical, preferably --COOH, --CONH. sub. 2 or --COOR. sup. 6 ; R. sup. 3 is H or an organic radical, preferably methyl, other alkyl having up to about five carbon atoms, --CH. sub. 2 COOR. sup. 6, --COOR. sup. 6 or --CH. sub. 2 COOH; R. sup. 4 and R. sup. 5, individually, are monocyclic alkyl having six or more carbon atoms, acyclic alkyl having nine or more carbon atoms, or alkaryl having nine or more carbon atoms; R. sup. 6 is hydrocarbyl, preferably alkyl; n has a value from zero to about ten; (b) vinyl esters of alkanoic acids having at least eight carbon atoms; (c) substituted styrenes wherein the substituent group or groups have a total of three or more carbon atoms; and mixtures thereof; said polymer having surface energy properties such as to form a stable bond with said substrate. The polymer, used alone or in a blend, serves as a coating, a tiecoat, an adhesive or a binder.
