ABSTRACT:
Disclosed are a block-graft copolymer comprising a polymer block having a repetitive unit represented by General Formula: ##STR1## wherein A represents an organopolysiloxane chain, a polyalkylene oxide chain, a polyalkylene-imine chain, a polyacrylate chain or a polyacryloyl chain,
and a process for producing the same. This block-graft copolymer can have various performances such as an oxygen enrichment performance, an ion concentration property, a capability of forming a complex with a metal salt and a biocompatibility, depending on the kind of graft polymer chains.
