Filler-containing polymer particles useful as carriers for supporting a biological substance.

摘要

Polymer particles comprising a polymer of an ethylenically unsaturated compound in which a silicon compound having an alkenyl group or 15% by weight or more of a polyfunctional ethylenically unsaturated compound has been polymerized or copolymerized having a filler dispersed therein, or polymer particles consisting of (I) said polymer particles having formed on their surfaces (II) a layer of a filler-free polymer of an ethylenically unsaturated compound are useful as a carrier for supporting a biological substance.
