The use of liquid media in kolloidoploselige or suspendible particles of physiologically tolerable polymer material in combination with the biologically active material

摘要

There are described processes for the preparation of submicroscopic particles of physiologically acceptable polymer associated with a biologically active material, by polymerizing a monomer in the presence of the biologically active material or by adsorbing the biologically active material upon preformed submicroscopic polymer particles. Where the biologically active material is an antigen, the particles are useful as constituents of injectable vaccines having an adjuvant effect.
