Document Type and Number:
Japanese Patent JP2564386
Kind Code:
B2
Abstract:
A water-insoluble polymer powder that can be redispersed in a liquid phase is obtained by proceeding as follows: first prepare a two-phase liquid-liquid system from a concentrated aqueous solution of a solute and a solution of the polymer in an organic solvent which is at least partially miscible with water, and then add water to it until all of the organic solvent has diffused into the aqueous phase. The polymer microparticles are then washed and dried. When resuspended in water, they result in a pseudo-latex.
