    摘要： Microbiological control is achieved by continuously and inexpensively dosing water in contact with biofilm, or that comes into contact with biofilm, using a highly effective biocide that provides very effective microbiocidal control of planktonic microorganisms and of biofilm species, even where the biofilm infestations have been in existence for long periods of time and thus have encased themselves in a substantial quantity of slimy defensive polysaccharide layers or films. In addition, the biocide used makes possible significant reduction in copper and/or iron surfaces in contact with the water as compared to N,N′-bromochloro-5,5-dimethyl hydantoin. Still other advantages are made possible by the described technology.

    摘要： Novel polyurethane-ureas having superior high temperature performance are prepared by reacting an isomeric mixture of 3,5-di(methylthio)-2,6-diaminotoluene and 3,5-di(methylthio)-2,4-diaminotoluene with an alkyl-substituted aromatic diisocyanate prepolymer having a free --NCO content of 0.1-20% by weight, produced by the reaction of a mixture of 2,4- and alkyl-substituted 2,6-aryl diisocyanates with a polyether glycol. The polyurethane prepolymers have a free --NCO content of 2-10% by weight and contain from about 3 to about 20 weight percent of the polyether. These elastomers have good dynamic properties, such as resilience, that make them attractive as roller materials.

    摘要： Described are highly concentrated liquid biocidal solutions formed in water from (a) specified bromine sources (e.g., BrCl or mixtures of BrCl and Br2) and (b) alkali metal salt of sulfamic acid and/or sulfamic acid and alkali metal base, wherein the solution contains >160,000 ppm of active bromine. Solutions of this type have been found to have greater stability than a commercially-available solution made from the same components containing 148,600 ppm of active bromine. Also described are new, water-soluble, solid state biocidal products formed by removing the water from solutions made in water from (a) and (b) irrespective of the initial concentration of active bromine. Removal of water can be accomplished by flashing or distillation at reduced pressure or preferably by spray drying. Such solid state products are typically in the form of powders or small particles, but can be compacted into larger forms preferably with the aid of one or more suitable binding agents.
