Abstract
A process for the preparation of a fluoroolefin polymer from an azeotropic mixture of monomers having a constant composition, the process including the step of: contacting in a reaction zone: (i) an initiator; and (ii) an azeotropic mixture of monomers including at least one fluoroolefin and, optionally, at least one ethylenically unsaturated comonomer capable of copolymerizing therewith; wherein the contacting is carried out at a temperature, pressure and length of time sufficient to produce the fluoroolefin polymer.
Claims
exact text as granted — not AI-modified1 - 23 . (canceled)
24 . A homopolymer prepared by a process comprising a step of: contacting in a reaction zone: an initiator; and an azeotropic mixture of at least two monomers comprising at least one fluoroolefin and, optionally, at least one ethylenically unsaturated comonomer capable of copolymerizing therewith; wherein said contacting is carried out at a temperature, pressure and length of time sufficient to produce said fluoroolefin polymer.
25 . A copolymer prepared by a process comprising a step of: contacting in a reaction zone: an initiator; and an azeotropic mixture of at least two monomers comprising at least one fluoroolefin and, optionally, at least one ethylenically unsaturated comonomer capable of copolymerizing therewith; wherein said contacting is carried out at a temperature, pressure and length of time sufficient to produce said fluoroolefin polymer.
26 . A terpolymer prepared by a process comprising a step of: contacting in a reaction zone: an initiator; and an azeotropic mixture of at least two monomers comprising at least one fluoroolefin and, optionally, at least one ethylenically unsaturated comonomer capable of copolymerizing therewith; wherein said contacting is carried out at a temperature, pressure and length of time sufficient to produce said fluoroolefin polymer.
27 . A polymer blend comprising at least two polymers selected from the group consisting of: a homopolymer, copolymer, and terpolymer prepared by a process comprising a step of: contacting in a reaction zone: an initiator; and an azeotropic mixture of at least two monomers comprising at least one fluoroolefin and, optionally, at least one ethylenically unsaturated comonomer capable of copolymerizing therewith; wherein said contacting is carried out at a temperature, pressure and length of time sufficient to produce said fluoroolefin polymer.Cited by (0)
