Abstract

Porious spherical particles with mechanical strength and high autiabrasity and microbial affinity, useful as biological carrier. The process for preparing them with simplicity and high productivity is also disclosed. The porious spherical particles have polyvinyl acetal resin as skeleton, the porious rate being 50-95%, and acetalation 30-85 mol%. The particles can be made by dropping polyvinyl alcohol an aqueous solution of water solubity high molecular polymer and aldehydes into an acid solution and gelatin by the reaction of polyvinyl alcohol and aldehye.
