Radiation-induced terpolymerization of methyl. cap alpha. ,. beta. ,. beta. -trifluoroacrylate with tetrafluoroethylene and. cap alpha. -olefin. [. gamma. rays]
Radiation-induced terpolymerizations of methyl ..cap alpha..,..beta..,..beta..-trifluoroacrylate (MTFA) with tetrafluoroethylene (TFE) and ..cap alpha..-olefins, such as ethylene, propylene, and isobutylene, were carried out in bulk at 25/sup 0/C for the purpose of controlling the content of ester group in the MTFA-..cap alpha..-olefin alternating copolymers. These monomers polymerized to form alternating terpolymers which contained 50 mole % ..cap alpha..-olefin in a wide range of monomer composition. The content of MTFA, namely, the ester group in polymer, can be varied without destruction of the alternating structures between fluoroolefins (MTFA, TFE) and ..cap alpha..-olefin by changing the MTFA/TFE ratio in the monomer mixture. The relative reactivities of MTFA and TFE in the terpolymerization were discussed according to kinetic treatments by free propagating and complex mechanisms. The relation between the MTFA/TFE ratio in the monomer mixture and that in terpolymer was explained favorably by the complex mechanism. It was also concluded that the relative reactivity of MTFA is larger than that of TFE in the terpolymerizations.
