Patent ID: 6962966

Claim:
A monohydric polyfluorooxetane oligomer composition, comprising: a unit, derived from a fluorooxetane monomer, having the formula or combinations thereof, where R 1 is derived from a co-initiator solvent monoalcohol, wherein said composition is derived from a solution having less than about 10% by weight of a non-initiator solvent based upon the total weight of said non-initiator solvent and said monoalcohol, where Dp is from about 2 to about 20, where each n is the same or different and independently is an integer from 1 to about 6, R is hydrogen or an alkyl of 1 to 6 carbon atoms, and each Rf is the same or different and independently on each repeat unit is a linear or branched fluorinated alkyl of 1 to 20 carbon atoms, a minimum of 75 percent of the non-carbon atoms of the alkyl being fluorine atoms and optionally the remaining non-carbon atoms being H, I, Cl, or Br, and said monohydric polyfluorooxetane oligomer optionally including at least a comonomer unit derived from a monomer containing at least an epoxy (oxirane) functionality, a monomer having a 4-membered cyclic ether group (oxetane); a monomer having a 5-membered cyclic ether group, 1,4-dioxane, 1,3-dioxane, 1,3-dioxalane, trioxane, or caprolactone; or combinations thereof, in an amount of from about 0.1% to about 10% by weight based upon the total weight of said comonomer and said fluorooxetane monomer, and said composition having less than about 10% by weight of a cyclic oligomer therein based upon the total weight of said oligomer, and any polymer, or copolymer produced.
