标题:High capacity methods for separation, purification, concentration, immobilization and synthesis of compounds and applications based thereupon
发明人：LEE WILLIAM; SAITO KYOICHI
摘要:Compositions are provided herein comprising a base material having engrafted polymer brushes. The polymer brushes further comprise one or more functional groups immobilized along the surface of the brushes in a plurality of layers, which confer functional properties to the base material compositions. Methods of using these compositions include deoxygenation of a sample solution, hydrolysis of denaturing agents in a sample solution, resolution of racemic mixtures in a sample solution, and purification, and concentration of target compounds.

标 题 :Polymerization of olefins
发明人：BROOKHART MAURICE S; JOHNSON LYNDA KAYE; KILLIAN CHRISTOPHER MOORE

摘要:Disclosed herein are processes for polymerizing ethylene, acyclic olefins, and/or selected cyclic olefins, and optionally selected olefinic esters or carboxylic acids, and other monomers. The polymerizations are catalyzed by selected transition metal compounds, and sometimes other co-catalysts. Since some of the polymerizations exhibit some characteristics of living polymerizations, block copolymers can be readily made. Many of the polymers produced are often novel, particularly in regard to their microstructure, which gives some of them unusual properties. Numerous novel catalysts are disclosed, as well as some novel processes for making them. The polymers made are useful as elastomers, molding resins, in adhesives, etc. Also described herein is the synthesis of linear α-olefins by the oligomerization of ethylene using as a catalyst system a combination a nickel compound having a selected α-diimine ligand and a selected Lewis or Bronsted acid, or by contacting selected α-diimine nickel complexes with ethylene.

权利人:CIBA SC HOLDING AG
摘要:The present invention relates to a polymerizable composition comprising a) at least one ethylenically unsaturated monomer and b) at least one hydroxylamine of high molecular weight, preferably a long chain alkyl substituted hydroxylamine. Further aspects of the present invention are a process for polymerizing ethylenically unsaturated monomers, and the use of high molecular weight hydroxylamines for controlled polymerization.

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.
