Abstract
Provided are core/shell type polymeric particles including a shell and a core, in which the particles can be produced by a method using neither a surfactant nor a high-molecular-weight azo initiator, exhibit satisfactory dispersibility in aqueous medium, and are useful as, for instance, a dispersant, a metal-protecting stabilizer, or a metal adsorbent. A core/shell type polymeric particle including a shell including a hydrophilic vinyl ether polymer (a) and a core including a hydrophobic polymer (b).
