Kinetics of radiation-induced cotelomerization of tetrafluoroethylene with methyl acrylate and terafluoroethylene with acrylamide in solutions of methylene chloride was studied. The synthesis process occurs under the conditions of kinetic chain transfer to the telogen, which involves only the radical with a terminal fragment of tetrafluoroethylene, whereas methyl acrylate or acrylamide molecules are added to the growing telomer chain. The composition of the telomer and its properties depend on the relative reactivities of the monomers in the chain-growth reaction. The incorporation of methyl acrylate into the telomer chain results in that the molecular mass and the fraction of the soluble fraction of the cotelomer become larger. It was found that the adhesion properties of fluorine-containing coatings formed on the basis of cotelomers of tetrafluoroethylene and methyl acrylate are improved.
