摘要： The present invention provides a polymerizable monomer composition particle and a resin particle, both of which display a narrow particle diameter distribution. A process for producing a resin particle comprises the steps of: passing two liquids through a static type in-line mixer having a liquid-dividing mechanism standing in a static state, wherein the two liquids are formable into two phases including one of the two liquids as a dispersing phase component and the other as a continuous phase component; then passing the two liquids through a high speed shearing type dispersing machine having a liquid-shearing mechanism which revolves at a high speed, thus dispersing a fine liquid drop of the dispersing phase component into the continuous phase component; and forming a resin particle from the resultant liquid drop.

摘要： To efficiently dry it, a nonionic alkylene oxide-type water-soluble resin is put into a container, then the container is degassed to a prescribed vacuum degree which is maintained while a dry gas having a dew point not higher than prescribed is introduced into the container at a rate not lower than prescribed. Minor volatiles are efficiently removed from the resin in an evaporation tank having a stirring blade. For protecting the dried resin from water, a dry gas is introduced into and air is purged from an empty packaging container whereafter the resin is charged into the container is sealed. By controlling solvent content and visocity of the resin and loading it into a temperature-controlled transportation container and/or unloading it out of the transportation container by the use of a pump, good subsquent processability of the resin and prevention of deterioration thereof are ensured.

摘要： The residual amount of a solvent in a water soluble nonionic alkylene oxide resin is decreased in an apparatus including an evaporation vessel and a stirring blade which scrapes-up and coats resin solution onto the inner wall surface of the evaporation vessel. A water soluble nonionic alkylene oxide resin having a crystallization temperature of 10 to 60° C. is extruded to a predetermined thickness in a molten state, the extruded molten resin is brought into contact with a metal surface which is at the crystallization temperature (Tc) or lower, and the thereby solidified resin may be cut into pellets. The resin pellets preferably are of rectangular shape and prescribed dimensions. The resin may be pulverized in a pulverizer by shearing force between a rotary blade and a fixed blade. In the pulverizer, grains smaller than a predetermined size pass through the screen, while larger grains are again pulverized.
