    摘要： An object is to provide fine resin particles that have solvent resistance sufficient to withstand a heating step after solvent dispersion and that generate few bubbles during dispersion and have high dispersibility in a solvent, and a method for producing the fine resin particles. As a solution, fine resin particles obtained by polymerizing a vinyl monomer, the fine resin particles having a gel fraction of 93% or more and a solvent resistance index of 50 or less, and fine resin particles obtained by polymerizing a vinyl monomer, in which the vinyl monomer contains a reactive surfactant having a polyoxyalkylene chain in a molecule thereof, and a vinyl polymer chain of the fine resin particles is terminated with a hydroxy group derived from a polymerization initiator, are provided.

    摘要： To provide a process for concentrating and recovering a surfactant aqueous solution, by which a surfactant aqueous solution can be evaporated and concentrated while suppressing foaming, and a surfactant aqueous solution in which the concentration of the surfactant is increased, can easily be obtained with high efficiency. A process for concentrating and recovering a surfactant aqueous solution, by evaporating and concentrating a surfactant aqueous solution containing a gasifiable surfactant and an aqueous solvent to increase the concentration of the surfactant, which comprises storing the surfactant aqueous solution in an evaporator 12; adjusting the temperature of the surfactant aqueous solution in the evaporator 12 to be lower than the boiling point of the aqueous solvent under the pressure in the evaporator 12; withdrawing a part of the surfactant aqueous solution from the evaporator 12, superheating it by a superheater 14 under conditions that all the surfactant and the aqueous solvent are formed into an annular flow or an annular mist flow, and spraying it from a nozzle 32 having a shape such that the outlet side first narrows and then widens outward, into the evaporator 12; and evaporating and removing the aqueous solvent.
