PROCESS FOR THE PREPARATION OF COPOLYMERS OF POLYSACCHARIDES AS SUPPORTS OF ENZYMATIC ACTIVITY AND COPOLYMERS THUS OBTAINED ABSTRACT OF THE DISCLOSURE A process for the preparation of a copolymer of a polysaccharide having enzymatic activity is described which comprises adding to a suspension of a polysaccharide in an aqueous medium, a vinyl monomer and an enzyme, then a catalyst which comprises a metallic salt and irradiating the resulting mixture with a source of ultravlolet light. The metallic salt is preferably a ferric salt. The vinyl monomer may be methylacrylate, glycidylmethacrylate, acrylonitrile, bis-acryloylpiperazlne or symmetrical N,N',N"-trisacryloyl- hexahydrotriazine. The process is applicable to a great variety of enzymes such as proteolytic enzymes, hydrolytic enzymes, oxidases, dehydrogenases and isomerases.
