Experimental results are presented showing the possibility of porphyrins immobilization on the sur- face of polypropylene activated by plasma chemical methods. Treatment of polymer in low-pressure oxygen plasma, in plasma afterglow or in plasma – solution system was used for the surface activation. Bonding of porphyrins with the activated surface was found to be partially reversible. Influence of the parameters of plasma chemical activation on the efficiency of porphyrin grafting has been studied. Results obtained by the modification of polymer in the plasma – solution system and in the low-pressure oxygen plasma are com- pared.
