POLYMERIC CARRIERS FOR COVALENT IMMOBILIZATION OF AMINO-GROUPS CONTAINING COMPOUNDS

Graft copolymers of acryloylchloride (AC) with polyethylene (PE) and p olyethyl eneterephtalate (PET) have been synthesized by grafting of AC from the vapor phase under mutual gamma-irradiation. It has been show n that both the amount of grafted reactive chains and their structure was determined by the polymer: monomer ratio and the total irradiation dose. The high grafting degree of reactive groups and their ability t o interact with free amino groups of biological molecules both in orga nic media and in water solutions make these functionalized polymers su itable as reactive carriers for covalent immobilization of various ami no groups containing compounds.
