摘要：
A particulate polymer which has imide groups and may be in gelled state can be produced by reacting a polyisocyanate with a polycarboxylic acid having at least one acid anhydride group, and if necessary together with a polycarboxylic acid other than that mentioned above in the presence of a liquid medium containing at least one non-aqueous organic liquid, and thereby obtaining the particulate polymer having imide groups dispersed in the non-aqueous organic liquid.
