摘要： PROBLEM TO BE SOLVED: To provide a material for simply producing an organic effective, colorants having no tendency to cause swelling in an organic solvent and aqueous one at a low cost. SOLUTION: This core-shell particle can form a two-phase system. The shell material is filmable. The core is essentially stable in shape under shell- filming conditions, only sparingly causes swelling due to the shell material even if swelling occurs and has monodisperse size distribution. There is difference in index of refraction between the core material and the shell one.

摘要： Bei einem Verfahren zur Herstellung wiederverwertbarer Faserverbundwerkstoffe, bei dem Fasern mittels eines polymeren Bindemittels miteinander verbunden werden, wird als Bindemittel eine wäßrige Polymerisatdispersion eingesetzt, die einen bei Anwendungstemperatur filmbildenden Polymerisatanteil in disperser Verteilung mit der Maßgabe enthält, daß die Gesamtmenge des in der wäßrigen Polymerisatdispersion in disperser Verteilung enthaltenen, bei Anwendungstemperatur filmbildenden Polymerisatanteils bei pH-Änderung des wäßrigen Dispergiermediums in eine wäßrige Polymerisatlösung übergeht. Dabei kann der bei Anwendungstemperatur filmbildende Polymerisatanteil der wäßrigen Polymerisatdispersion protische Säuregruppen aufweisen, und seine disperse Verteilung im wäßrigen Medium kann durch Erhöhung des pH-Werts des wäßrigen Mediums in eine wäßrige Polymerisatlösung übergehen, oder er kann basische Gruppen aufweisen, insbesondere Aminogruppen, und seine disperse Verteilung kann im wäßrigen Medium durch Absenkung des pH-Werts des wäßrigen Mediums in eine wäßrige Polymerisatlösung übergehen.

The initiator or oxidation component is a long-chain compound which is a surface-active initiator (inisurf) with a hydroperoxide, peroxo or azo group or a surface-active hydroperoxide- or peroxo-group-containing compound.- DETAILED DESCRIPTION - Post-polymerisation reduction of the residual monomer content of an aqueous polymer dispersion obtained by free radical polymerisation of olefinically-unsaturated monomers comprises adding an initiator or an oxidation component of a redox system (together with a reduction component and optionally catalytic metal ions in the latter case), the added initiator or oxidation component being a long-chain compound which is: - (A) a long-chain, surface-active initiator (inisurf) with a hydroperoxide, peroxo or azo group, or - (B) a long-chain, surface-active hydroperoxide- or peroxo-group-containing compound obtained (optionally in situ) by oxidation of optionally modified autooxidizable olefinically-unsaturated fatty acids, fatty acid compounds, fatty alcohols or hydrocarbons.TF - TECHNOLOGY FOCUS - POLYMERS - Preferred materials: Both (A) and (B) contain at least 12C.- The azo group-containing (A) compounds are obtained by coupling a long-chain hydrophobic paraffin residue with an azo compound and the hydroperoxide- or peroxo-group-containing (A) compounds are reaction products of hydroperoxides or H2O2 with cyclic anhydrides of carboxylic or sulfonic acids containing an at least 12C paraffin hydrophobic group.- Typical (A) include reaction products of 1 mol. azobutyric acid diamidine dihydrochloride and 2 mols. tetradecylsulphonyl chloride (EP65136) and the equimolar tetradecylsuccinic anhydride/tert. butyl hydroperoxide reaction products of EP569778.- (B) are obtained by oxidation of autooxidizable fatty-acids or-alcohols which have been adducted with 2-20 mol ethylene oxide and which have also optionally been finally modified by sulfation

摘要： In order to prepare an antibacterial and fungicidal polymer dispersion, a polymer dispersion is mixed with an amount of a protective polymer which is dispersible in the polymer dispersion, said amount being sufficient to attain an antibacterial and fungicidal effect. The protective polymer comprises: between 3 and 60 wt %, relative to the total weight of components a) and b) without metallic ions, of at least one C3 to C7 alpha, beta-monoethylenically unsaturated mono or dicarboxylic acid which is partially or completely neutralized or can be present as an anhydride, as component a); between 97 and 40 wt %, relative to the total weight of components a) and b) without metallic ions, of at least one C1 to C20 alkyl(meth)acrylate, of a C1 to C20 carboxylic acid vinyl ester, of a vinyl aromatic containing up to 20 carbon atoms, of an ethylenically unsaturated C3 to C6 nitrile, of a vinyl halide or a non-aromatic C4 to C8 hydrocarbon and at least two conjugated double bonds or ethylene or propylene as component b); between 0 and 50 wt %, relative to the total weight of components a) and b) without metallic ions, of at least one further ethylenically unsaturated monomer, as component c); and between 0 and 20 wt %, relative to the total weight of components a), b) and c) without metallic ions, of at least one cross-linking polyfunctional monomer, as component d). Between 1 and 100 mol % of the acid groups are converted into salts of at least one antibacterial and/or fungicidal metallic ion.

摘要： Method of reducing the residual monomer (I) content in a solution, mixture, melt, suspension or dispersion of a polymer produced by free radical polymerization (liquid system). The process involves adding a nucleophilic agent (II), which forms an adduct with (I) at the reaction temperature, in an amount of 0.5-5 mole (II) /mole (I). The novelty is that (II) is stirred gradually into the liquid system in a production reactor with a height/diameter ratio of 0.8-4 in a dosing time not less than the shortest possible mixing time.

摘要： A process for the prodn. of reusable fibre composite materials (FCM) contg. fibres (I) bonded together with a polymeric binder is claimed. The binder consists of an aq. dispersion of a polymer (II) which is film-forming at usage temps. and which goes entirely into soln. when the pH of the dispersion medium is changed. Also claimed is (i) material (FCM) obtd. by this process, esp. in the form of non-woven fabric or paper, and (ii) a process for recycling FCM, in which the FCM is treated with an aq. medium at a pH such that polymer (II) is dissolved to give fibres and binder soln., which are then sepd. and reused.
