A porous polymer containing immobilized enzymes or bacteria cells is prepared by forming a mixture of enzymes or bacteria cells and a monomer having the formulae <IMAGE> <IMAGE> wherein X is hydrogen or methyl; R is -CH2CH2-, <IMAGE> or -CH2CH2CH2-, R' is alkyl or hydrogen; n is integer of 2 or more and m is integer of 4 or more, or mixture of such monomers; and then polymerizing or copolymerizing the monomer(s) in the mixture at a temperature of less than 0 DEG C. by means of ionizing radiation. |
