CROSS-LINKED POLYMER PARTICLE AND METHOD FOR PRODUCING SAME

摘要

Disclosed is a cross-linked polymer particle that can be obtained by a production method provided with a step (a) in which a mother particle formed from a cross-linked polymer having functional groups is brought into contact with an amino compound having two or more amino groups, and the cross-linked polymer is further cross-linked by a reaction of the functional groups and amino groups. This amino compound includes low molecular weight amino compounds with molecular weights less than 500.
