Experimental results of heavy ion (1.0-5.6 MeV/amu) radiolysis investigations of polyvinilidenefluoride and some copolymers of vinylidenefluoride have been presented. The formation of conjugated C=C double bonds, the growing of number of these bonds' with the increasing REL have been confirmed by the UV-and IR-spectroscopy methods. It has been found that along with the formation of conjugated double and the triple alkine bonds in copolymers of vinylidenefluoride with hexafluoropropylene and trifluorochloroethylene arise, but their quantities are low. The ratio between destruction and crosslinking processes as a function of heavy ions REL value has been evaluated by means of viscosimetry and gel-fraction method. The composition of the etching solution for technological process of track membranes manufacturing according to the obtained data has been proposed. This technology allows one to manufacture fluoropolymer track membranes with pore sizes from 0.1 to some micrometers, different shapes and narrow pore size distribution.
