MALEIMIDE GROUP-CONTAINING CROSSLINKED POLYMER PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a maleimide group-containing crosslinked polymer particle having good water-dispersibility. SOLUTION: The maleimide group-containing polymer particle contains at least the maleimide group and a hydroxy group regulated so that the ratio (A) of contents of the maleimide group to the hydroxy group (the molar ratio of maleimide group/hydroxy group) may satisfy the inequality: 0.01
