Patent application numberDescriptionPublished
20080207838CONTINUOUS PROCESS FOR THE PREPARATION OF A REACTIVE POLYMER - A continuous process for the reactive compatibilization of polymers includes I. processing monooxazoline, bisoxazoline or a mixture thereof together with a first polymer, to give a reactive polymer; and II. adding the reactive polymer to one or more second polymers. In addition, a reactive polymer contains I. a first polymer; and II. at least 5% by weight of chemically unbound monooxazoline, bisoxazoline or a mixture thereof.08-28-2008
20080214864CONTINUOUS PROCESS FOR DECARBOXYLATING CARBOXYLIC ACIDS - A continuous process for decarboxylating carboxylic acids proceeds by I.) initially charging a carbonyl compound as a catalyst in a solvent at reaction temperature, to obtain a catalyst solution; II.) metering a carboxylic acid into the catalyst solution as an aqueous solution, aqueous suspension or as a water-comprising solid, to obtain a reaction mixture; and III.) continuously removing a mixture of CO09-04-2008
20080221365PROCESS FOR STABILIZING CYCLOBUTANONE DERIVATIVES - A process for stabilizing cyclobutanone derivatives, comprising adding at least one of an alkali metal carbonate, alkali metal oxide, alkaline earth metal carbonate, and alkaline earth metal oxide as a stabilizer to at least one cyclobutanone derivative of the structure09-11-2008
20080281126PROCESS FOR PREPARING AMINES - An amine is prepared by cleaving a carbamate of the formula I11-13-2008
20090318648MEDIA-RESISTANT COATING RESINS - The invention relates to compositions comprising glycerol mono(meth)acrylate and hydroxyethyl methacrylate, including those with addition of further monomers, free-radically polymerized and subsequently crosslinked with isocyanates, to a process for preparing them and to their use as film-forming resins with particular media resistance.12-24-2009
20100076186PROCESS FOR PREPARING HETEROCYCLES - Provided is a process for preparing a heterocycle by catalytic reaction of an aromatic dinitrile with an amino alcohol, wherein the process includes: initially charging into a reaction vessel the amino alcohol and a catalyst to produce a reaction mixture; adding the aromatic dinitrile into the reaction mixture, which is maintained at a reaction temperature, wherein no solvent other than the amino alcohol of formula (III) is added to the reaction mixture prior to and/or during the catalytic reaction; and after completion of the catalytic reaction, completely replacing, or substantially completely replacing, unreacted amino alcohol with a nonpolar solvent to obtain the heterocycle, wherein the unreacted amino alcohol is present in an amount of not more than 20 wt. %, preferably 3-10 wt. % or less, based on a total weight of the heterocycle.03-25-2010
20110046332HYDROGEL BASED ON COPOLYMERS CONTAINING SILICONE - The invention relates to a hydrogel which is a copolymer formed from a polymerizable monomer mixture which contains 02-24-2011
20110152411POLYMER COMPOSITION COMPRISING PHENOLIC RESIN - The invention relates to a polymer composition which is characterized in that it comprises a mixture (A) consisting of formula (A1)) and/or formula (A2), phenolic resin (B) and a stabilizer (C) in the form of a HALS compound06-23-2011
