| titleOfInvention | A fluorinated pentadiene derivative and polymers thereof |
| abstract | The invention comprises the compound 3,4, 5,5,5-pentafluoro-1, 3-pentadiene and polymers thereof (see Division C3). The compound may be prepared (a) by reacting ethanol with perfluoropropene in contact with an organic peroxide catalyst to form 3,3,4,5,5,5-hexafluoro-2-pentanol which is treated with phosphorus pentoxide to produce 3,3,4,5,5,5-hexafluoro -1- pentene which is then treated with a base to give the desired product, or (b) by the addition of 1-bromo-1, 1, 2, 3, 3, 3-hexafluoropropane to ethylene in the presence of an organic peroxide to give 1-bromo-3, 3, 4, 5, 5, 5-hexafluoropentane which on dehydrobromination and dehydrofluorination with a base yields the desired product. Examples are given.ALSO:The invention comprises polymers of 3,4,5,5,5- pentafluoro-1, 3-pentadiene. The polymers may be prepared by polymerizing the monomer, for example in the presence of ultra-violet radiation. An example is given. |
