<p><P>PROBLEM TO BE SOLVED: To provide a crosslinked polymer particle powder excellent in the dispersion into an organic solvent, a molten resin, and the like, and a manufacturing method therefor. <P>SOLUTION: The crosslinked polymer particle powder contains 100 pts. mass of a crosslinked polymer particle and 1-100 pts. mass of a dispersant shown by the formula (1): T<SP>1</SP>O-(RO)<SB>n</SB>(EO)m-T<SP>2</SP>(1). In the formula (1), T<SP>1</SP>is hydrogen atom, a 1-18C alkyl group or a 2-18C alkenyl group; T<SP>2</SP>is hydrogen atom, sulfonic acid (sulfonate) group, carboxylic acid (carboxylate) group, phosphoric acid (phosphate) group, amino group or ammonium group; RO is a 3-18C oxyalkylene group; and EO is an oxyethylene group. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
