  • Antimicrobial material for breeding or keeping fish and process for producing the same
    Patent number: 5364638
    Abstract: An antimicrobial material for fish breeding or keeping comprising a formed article of a pulp and/or polyolefin base material and a process for producing the same are disclosed, in which said formed article contains a functional group having a function of removing harmful ions combined with an antimicrobial activity. The material is produced by graft polymerizing a reactive monomer on a formed article of a pulp and/or polyolefin base material and introducing a functional group having a function of removing harmful ions combined with an antimicrobial activity into the grafted chain of the graft polymer. By the use of the material, fish keeping including transportation can be carried out stably and efficiently.
