Abstract
A process for the preparation of a fluoroolefin polymer, including the step of: contacting in a reaction zone: an initiator; CF3CF═CH2, 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.

A process for the preparation of a fluoroolefin polymer, comprising the step of:
- contacting in a reaction zone:
- an initiator;
- CF3CF═CH2, and
- at least one ethylenically unsaturated comonomer selected from the group consisting of acrylate, methacrylate or α-trifluoromethylacrylate ester of 4 to 24 carbon atoms, hydroxyethyl acrylate, methacrylate or α-trifluoromethylacrylate, hydroxypropyl acrylate, methacrylate or α-trifluoromethylacrylate, glycidyl acrylate, methacrylate or α-trifluoromethylacrylate, and acrylonitrile, methacrylonitrile, wherein said contacting is carried out at a temperature, pressure and length of time sufficient to produce said fluoroolefin polymer.
