CORE/SHELL TYPE POLYMER MICROPARTICLES, DISPERSION OF PARTICLES, AND METHOD FOR PRODUCING SAID MICROPARTICLES

摘要

Provided are core/shell type polymer microparticles each comprising a shell and a core, the microparticles being able to be produced by a method in which neither a surfactant nor a high-molecular-weight azo initiator is used, showing satisfactory dispersibility in aqueous media, and being useful as a dispersant, a metal-protecting stabilizer, a metal adsorbent, etc. The core/shell type polymer microparticles each comprise a shell comprising a hydrophilic vinyl ether polymer (a) and a core comprising a hydrophobic polymer (b).
