Abstract

Hexafluoropropylene oxide is polymerized at - 80 DEG to +50 DEG C. by contact with (a) a monovalent metal fluoride dispersed in an organic polar solvent; (b) a quaternary ammonium, pyridinium, phosphonium or arsonium salt dispersed in an organic polar solvent; (c) a tertiary amine dispersed in an organic polar solvent; (d) a tertiary amine oxide dispersed in an organic polar solvent; (e) a quaternary ammonium, pyridinium, phosphonium or arsonium salt dispersed in a C5- 12 hydrocarbon solvent; or (f) a quaternary ammonium, pyridinium, phosphonium or arsonium salt dispersed in a solvent of formula R1R2CHCl, where R1 is H or Cl and R2 is H, Cl or C1- 12 haloalkyl; an organic polar solvent being defined as one which is liquid at reaction temperature and which dissolves CF3CF2CF2OK to a concentration of at least 0.01% by weight. Many components are specified for the catalyst compositions.ALSO:Hexafluoropropylene oxide is polymerized at -80 DEG to +50 DEG C. by contact with one of the group (a) or monovalent metal fluoride dispersed in an organic polar solvent; (b) a quaternary ammonium, pyridinium, phosphonium or arsonium salt dispersed in an organic polar solvent; (c) a tertiary amine dispersed in an organic polar solvent; (d) a tertiary amine oxide dispersed in an organic polar solvent; (e) a quaternary ammonium, pyridinium, phosphonium or arsonium salt dispersed in a C5- 12 hydrocarbon solvent; (f) a quarternary ammonium, pyridinium, phosphonium or arsonium salt dispersed in a solvent of formula R1R2CHCl, where R1 is H or Cl and R2 is H, Cl or C1- 12 haloalkyl; an organic polar solvent being defined as one which is liquid at reaction temperature and which dissolves CF3CF2CF2OK to a concentration of at least 0.01% by weight.
