The basic element of the synthesis ­ track membrane have to have various properties. The methods of chemical modification ­ is one of the simple ways to give the membranes the required physical-chemical properties. The methods of polyethilenetherephtalate track membranes surface modification with water-soluble polymers were developed. The modifying agents were different poly-Nvinylamides, polyvinyl alcohol, polyethylene glycol, heparin. Depending on the modifying agent it was possible to change controllably both the template surface charge sign and its value and the surface adsorption activity regarding model adsorbates (proteins and dyes). The modification regimes that allowed to decrease (down to 30 times) the adsorption loss of the adsorbates on the track template surface were found. The developed modification methods did not lead to essential changes of pores geometry of track ultra- and microfiltrational membranes that are used in template synthesis. Key words: template synthesis, track membranes, water-soluble polymers, chemical modification of surface, adsorption.
