RESIN POWDER CONTAINING ALUMINUM SALT, PROCESS FOR PRODUCTION OF THE SAME, AND RESIN COMPOSITION, PHOSPHOROUS ADSORBENT, ANTIBACTERIAL AGENT OR ANTIFUNGAL AGENT COMPRISING THE SAME

摘要

An aluminum salt-containing resin powder of the present invention includes at lest one matrix resin component selected from regenerated collagen, polyvinyl alcohol and carboxymethyl cellulose; and an aluminum salt. The aluminum salt is chemically bonded to the matrix resin component, and the resultant is powdered. A resin composition of the present invention includes 0.1 wt% or more and 80 wt% or less of the aluminum salt-containing resin powder and 20 wt% or more and 99.9 wt% or less of a resin other than the aluminum salt-containing resin. Thus, the present invention provides an aluminum salt-containing resin powder having a high phosphorus adsorption property, a high antibacterial property and a high antifungal property, and a resin composition containing the aluminum salt-containing resin powder.
