start with? How do I know it is feasible?
any expert has suggestion? thanks in advance.
for example:
-[ CF2CF ]n-

[CF2CF2]m-O-CF2CF2CN | C***S

maybe you can get some idea from there.
BTW: if you got this synthesized, please be kind to give me something
for NMR study.

BTW: I am not doing synthesis. That is just my curiousity.

where can I find related reference talking about this?
especially flurorited polymer?

Brice, T. J., and Pearlson, W. H., US Patent 2,713,593, assigned to Minnesota
Mining and Manufacturing Coop., July 1955.
I got this information from the following book:
Fluoroplastics, Volume 1, Non-Melt Processing Fluoroplastics.
ISBN:1-884207-84-7
Anothee books about Fluoropolymer may also help:Modern Fluoropolymers.
