The CO_2 laser-induced radical-chain reactions between CH_3CF_2H and chlorine-atom donors CF_2ClCFCl_2, CF_3CCl_3 CFCl_3 or CF_2Cl_2

The CO_2 laser induced room temperature reactions of CH_3CF_2H or another protium-donorCH_3CHClCH_3 with chlorine-atom donors (Z--Cl) CFCl_2CF_2Cl, CF_3CCl_3, CFCl_3 or CF_2Cl_2, havebeen investigated. Some of these reactions can yield two important monomers (CF_2=CH_2 andCF_2=CFCl) for fluoropolymers simultaneously. The yield dependence of these two alkenes on experi-mental conditions has been studied. A laser-initiated chain process is supported by identifica-tion of Z--H intermediates in these reactions.

The CO2 laser-induced radical-chain reactions between CH3CF2H and chlorine-atom donors CF2ClCFCl2, CF3CCl3 CFCl3 or CF2Cl2

The CO₂ laser induced room temperature reactions of CH₃CF₂H or another protium-donor CH₃CHClCH₃ with chlorine-atom donors (Z—Cl) CFCl₂CF₂Cl, CF₂CCl₃, CFCl₃ or CF₂Cl₂, have been investigated. Some of these reactions can yield two important monomers (CF₂ = CH₂ and CF₂ = CFCl) for fluoropolymers simultaneously. The yield dependence of these two alkenes on experimental conditions has been studied. A laser-initiated chain process is supported by identification of Z—H intermediates in these reactions.
