Abstract
Compositions and methods of producing the same are provided. In an exemplary embodiment, a composition includes a high temperature PCTFE (poly chlorofluoro ethylene) produced by a high temperature process. The high temperature PCTFE includes some fluorine endcaps. The composition also includes a low temperature PCTFE produced by a low temperature process.
Claims20
A composition comprising:
- a high temperature PCTFE (poly chlorotrifluoro ethylene) produced by a high temperature process;
- and
- a low temperature PCTFE produced by a low temperature process.
A composition comprising:
- a pristine poly chlorotrifluoro ethylene (PCTFE), wherein the pristine PCTFE comprises carboxylic acid endcaps;
- and
- a fluorinated PCTFE, wherein the fluorinated PCTFE comprises fluorine endcaps.
A method of producing a composition comprising:
- providing a pristine poly chlorotrifluoro ethylene (PCTFE) having a carboxylic acid endcap;
- exposing the pristine PCTFE to a gas comprising fluorine and nitrogen at a temperature of from about 210 to about 290 degrees Celsius to produce high temperature PCTFE;
- and
- blending the high temperature PCTFE with a type of PCTFE that is different than the high temperature PCTFE.
