摘要:In one aspect, the present invention is directed to dendrimers comprised of macromolecules and trifunctional branches. In another aspect, the invention relates to methods for generating dendrimeric compositions comprising macromolecules and trifunctional branches. In certain embodiments, the radial density of the dendrimeric composition is controlled by selective incorporation of branches.

标 题:Removal of acrylonitrile from latex with saturated heterocyclic amines
发明人：SENYEK MICHAEL L
权利人:GOODYEAR TIRE & RUBBER
摘要:Acrylonitrile is a monomer that is widely used in the synthesis of a vast variety of polymers. Undesirable quantities of unpolymerized residual acrylonitrile are often present in these acrylonitrile polymers. This residual or free acrylonitrile dissolved in an acrylonitrile polymer and/or its emulsifier system and the water phase used in its polymerization can be reduced significantly in concentration by treatment with saturated 6 to 7 membered ring heterocyclic amines. These amines react with acrylonitrile by a nitrogen-cyanoethylation reaction which results in the formation of a tertiary amino linkage.

摘要:Acrylonitrile is a monomer that is widely used in the synthesis of a vast variety of polymers. Undesirable quantities of unpolymerized residual acrylonitrile are often present in these acrylonitrile polymers. This residual or free acrylonitrile dissolved in an acrylonitrile polymer and/or its emulsifier system and the water phase used in its polymerization can be reduced significantly in concentration by treatment with oximes. Oximes react with acrylonitrile by an oxygen-cyanoethylation reaction which results in the formation of a cyanoethyl oximino ether linkage.

摘要:A method for synthesising polymers through devulcanisation from waste containing elastomers, the method including:a) contacting the waste containing elastomers with a solvent in the presence of a devulcanisation agent,b) heating the mixture produced in step a), at a temperature of between 20° C. and 250° C. for a period of between 15 minutes and 24 hours in the presence of a devulcanisation agent, the concentration of devulcanisation agent, and the ratio between the concentration of devulcanisation agent, expressed as parts per hundred of elastomer (phr) and a volume of solvent, expressed in ml, is:greater than 0.3 phr/ml of solvent or less than 0.2 phr/ml of solvent when the method is carried out in air,greater than 0.06 phr/ml of solvent when the method is carried out in an inert atmosphere.

摘要:The present invention relates to novel Ruthenium catalysts and related borohydride complexes, and the use of such catalysts, inter alia, for (1) hydrogenation of amides (including polyamides) to alcohols and amines; (2) preparing amides from alcohols with amines (including the preparation of polyamides (e.g., polypeptides) by reacting dialcohols and diamines and/or by polymerization of amino alcohols); (3) hydrogenation of esters to alcohols (including hydrogenation of cyclic esters (lactones) or cyclic di-esters (di-lactones) or polyesters); (4) hydrogenation of organic carbonates (including polycarbonates) to alcohols and hydrogenation of carbamates (including polycarbamates) or urea derivatives to alcohols and amines; (5) dehydrogenative coupling of alcohols to esters; (6) hydrogenation of secondary alcohols to ketones; (7) amidation of esters (i.e., synthesis of amides from esters and amines); (8) acylation of alcohols using esters; (9) coupling of alcohols with water to form carboxylic acids; and (10) dehydrogenation of beta-amino alcohols to form pyrazines. The present invention further relates to the novel uses of certain pyridine Ruthenium catalysts.
