The polyethyleneterephtalate surface has been modified with new oligoperoxides, synthesized on the base of pyromellitic acid chloroanhydride, polyethylene glycol-9 and tert-butylperoxymethanole. The developed method allows to achieve the degree of surface modification up to 64 %. Ability of dextrane macromolecules attaching onto peroxidized surface has been shown. The correlation between the degree of surface modification and oligoperoxide concentration in solution, temperature and time of the modification process has been established.
