Title:
PRODUCTION OF FINE POWDER OF POLYMER CROSSLINKED BY METAL ION
Document Type and Number:
Japanese Patent JPH0665313
Kind Code:
A
Abstract:
PURPOSE: To produce the subject powder without damaging the polymer structure.
CONSTITUTION: A first aq. soln. contg. at least one metal hydroxide selected from the group consisting of an alkali metal hydroxide and an alkaline earth metal hydroxide and a raw material of a polymer crosslinkable by metal ions is reacted with a second aq. soln. contg. a metal salt by bringing the two solns. into contact with each other each in the form of mist.
