摘要： The presently claimed invention relates to the use of at least one compound of general formula (I) as an emulsifier or a stabilizer. The presently claimed invention further relates to the use of at least one compound of general formula (I) as an emulsifier or stabilizer in a polymerization reaction, preferably an emulsion polymerization. The presently claimed invention also relates to a method of emulsifying and/or stabilizing or dispersing liquids or solids in emulsion polymerization using at least one compound of general formula (I). Further, the presently claimed invention relates to a cleaning composition comprising at least one compound of general formula (I) and at least one additive.

摘要： The invention relates to a process for producing polymer composites suitable for absorbing and storing aqueous liquids, to the polymer composites obtainable by this process, and to the use of the polymer composites. The process comprises free-radical polymerization of a monomer composition M comprising 50 to 100% by weight, based on the total amount of monomers A and B, of at least one monomer A having one ethylenic double bond and at least one neutralizable acid group, 0 to 50% by weight of optionally one or more comonomers B which are different than the monomers A and have one ethylenic double bond, and 1 to 10% by weight, based on the total amount of monomers A and B, of at least one crosslinker C.

摘要： The invention relates to a process for producing polyarylene ether beads from a polyarylene ether solution, comprising the steps of i) dividing the polyarylene ether solution in a division apparatus which is made to vibrate with a frequency of 10 to 1400 Hz to obtain droplets, ii) transferring the droplets into a precipitation bath to form polyarylene ether beads in the precipitation bath which (A) comprises at least one aprotic solvent (component (1)) and at least one protic solvent (component (2)), (B) has a temperature of 0° C. to Tc, where the critical temperature Tc in [° C.] can be determined by the numerical equation Tc=(77−c)/0.58 in which c is the concentration of component (1) in the precipitation bath in [% by weight] and (C) has component (1) in concentrations of 5% by weight to cc, where the critical concentration cc in [% by weight] can be determined by the numerical equation cc=77−0.58*T in which T is the temperature in the precipitation bath in [° C.], where the percentages by weight are each based on the sum of the percentages by weight of component (1) and of component (2) in the precipitation bath.
