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.

1-23. (canceled)
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.
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.
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.
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.
