Notizen:
We have studied the copolymerization behavior of perfluoropropene, perfluorobutene-1, perfluorobutene-2, perfluoroisobutene, perfluoropentene-1, and perfluorononene-1. We have so far not succeeded in homopolymerizing these olefins. However, certain nonfluorinated, nonconjugated comonomers-ethylene, vinyl. chloride, vinyl acetate, and the vinyl alkyl ethers-were found to copolymerize readily, giving copolymers containing up to 50 mole per cent, and in some cases slightly more than this, of the perfluoro-olefin in the copolymer. The higher members of the series copolymerize in general less readily than the lower members. The products ranged from viscous oils to tough, film-forming solids. The difficulty of homopolymerization and the relative ease of copolymerization of the perfluoro-olefins with the above comonomers are discussed and interpreted in terms of probable electron distributions around the double-bond.
