Abstract
Chemical interaction of Ti metal with a tetrafluoroethylene-vinylidene fluoride copolymer (29 and 71 mol %, respectively) has been studied by differential scanning calorimetry, mass spectrometry, and nuclear magnetic resonance. The results indicate the formation of titanium trifluoride, a nonvolatile compound. The CF2 groups surrounded by CH2 groups in the polymer are the most reactive with titanium. The solid defluorination product is an aliphatic polyene containing C=C=C and C≡C-C bonds.
