Estimating the term…
Iodine containing amorphous fluoropolymers having at least one fluoropolymer with a cure site, where the fluoropolymer has a Mooney viscosity of 2 or less (ML 1+10) at 100° C. according to ASTM D1646, and a peel strength to a roll mill of 10 dN/cm or less and methods for making such iodine containing amorphous fluoropolymers are described. Articles derived from the cured product of such iodine containing amorphous fluoropolymers are also described. Solutions, dispersions and coatings derived from such iodine containing amorphous fluoropolymers are also described.
An iodine containing amorphous fluoropolymer composition comprising a first fluoropolymer having a cure site wherein the cure site is an iodine group derived from 1,4-diiodooctafluorobutane, and the cure site is present in an amount of from 0.25 to 1 mol %, further wherein the first fluoropolymer has a total weight percent of iodine of from 0.2 to 2 wt %, and further wherein the first fluoropolymer comprises repeating units derived from vinylidene difluoride and hexafluoropropylene and has a Mooney viscosity of 2 or less, ML 1+10, at 100° C. according to ASTM D1646-06 TYPE A, and further wherein the first fluoropolymer has a storage modulus at 25° C. and 6.3 rad/s of greater than or equal to 300 kPa and at 25° C. and 0.1 rad/s of less than or equal to 200 kPa.
