<P>PROBLEM TO BE SOLVED: To provide a spherical temperature-sensitive resin which adsorbs metallic ions, organic substances, etc. <P>SOLUTION: The spherical temperature-sensitive resin comprises a polymer prepared by polymerizing an N-alkyl(meth)acrylamide represented by formula (1) with a (meth)acrylic-group-containing phosphine polymer represented by formula (2) in the presence of a crosslinking agent. In the formulae, R<SP>1</SP>is a hydrogen atom or a methyl group; R<SP>2</SP>and R<SP>3</SP>are each a hydrogen atom or a 1 to 6C linear or branched alkyl group, provided that they can not be simultaneously; hydrogen atom R<SP>4</SP>is a methyl group or a hydrogen atom; A is a 1-10C linear or branched alkylene group; and R<SP>5</SP>is a hydrogen atom, a hydroxyl group, a 1-10C linear or branched alkyl group, a cycloalkyl group, a phenyl group; a substituted phenyl group, or a benzyl group. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
