Notizen:
Four new s-triazine polymers were prepared by the mercury-induced coupling of bromodifluoromethyl-substituted ditriazinyl-perfluoroalkane derivatives. Each polymer was composed of CF3-substituted s-triazin rings alternately joined with —CF2CF2—segments and \documentclass{article}\pagestyle{empty}\begin{document}$\hbox{---}\hskip-5pt({\rm CF}_2 )_8 \hbox{---}$\end{document}, a mixture of —(CF3CFO(CF2)5OCF(CF3)— and —(CF3)CFOCF2CF(CF3)OCF2)4—, —CF2OCF2—, or —CF2SCF2—, segments. All polymers were elastomeric and displayed high temperature stability on thermogravimetric analysis. The polymers containing either —CF2OCF2— or —CF2SCF2— segments showed high temperature limits slightly lower than the other two systems.
