Carrier-bound macromolecular compounds, especially bioactive macromolecular compounds, are produced by reacting a macromolecular compound A with a coupling compound B containing at least one reactive function capable of coupling with compound A and at least one further reactive function capable of polymerization, adding to the resulting coupled reaction product AB an unswollen molecular sieve material having cross-linking sufficient to exclude penetration by compound A, and polymerizing the polymerizable group of the coupled product AB in the molecular sieve material to form a polymer body in the molecular sieve material and fix compound A on the surface of the molecular sieve material. Compound A can be, e.g., an enzyme, antibody or hormone, and coupling compound B typically contains, as the coupable function, an alkylation or acylation group such as oxirane, ethyleneimine, halide, acid halide, azide or anhydride groups, and, as the polymerizable function, a carbon-carbon or carbon-oxygen double bond.

Preparation of carrier-bound macromolecular compounds

Carrier-bound proteins are prepared by reacting a protein in aqueous solution with a coupling compound having at least one group capable of acylating or alkylating proteins and at least one additional group capable of producing a bond with a carrier material, and reacting the resulting product with a carrier material, optionally forming the carrier material in situ by polymerization of a monomer or monomer mixture in the presence of said product.
