Abstract

Telomeres are formed under the action of gamma rays from a 60Co source at room temperature in solutions of tetrafluoroethylene in propylene oxide with concentrations of 0.08–4.2 mol/L; telomer chain length depends on the monomer content in the solution. Monomer consumption during irradiation was controlled calorimetrically and gravimetrically; its complete conversion is observed at irradiation doses of 10–15 kGy. Molecular-mass characteristics of radiolysis products were determined by thermogravimetry. The telomeres with chain length less than 6 form true solutions. At the degree of monomer polymerization 6–15 colloidal solutions are formed, at more than 15 – dense gels. In the structure of propylene oxide fluorotelomer, the end functional epoxy group is retained. The morphology of the coating layers was investigated by atomic force microscopy.
