Expandable functional TFE copolymer fine powder, expanded products and reacted products therefrom |
| 摘要 |
A functional TFE copolymer fine powder is described, wherein the TFE copolymer is a polymer of TFE and at least one functional comonomer, and wherein the TFE copolymer has functional groups that are pendant to the polymer chain. The functional TFE copolymer fine powder resin is paste extrudable and expandable. Methods for making the functional TFE copolymer are also described. The expanded functional TFE copolymer material may be post-reacted after expansion. |

1. An expanded copolymeric material comprising;
(a) a functional tetrafluoroethylene (TFE) copolymer material comprising:
a first portion comprising a polymer chain of TFE and at least two comonomers, each said comonomer having a functional group pendant to the polymer chain; anda second, shell portion comprising a functional TFE copolymer having high crystallinity; and (b) at least one additional fluoropolymer, wherein said at least two comonomers provide different functional groups. |
