Claim of US Patent No. 9,748,594

1. A method of manufacturing a polymer of fluorine-containing sulfonated poly(arylene ether)s, comprising steps of:
(S01) providing a fluorine-containing monomer having a structure given in the following formula (I):

wherein X is

D1 is halogen or hydroxyl group; and Z is independently selected from fluoro- or trifluoromethyl group;
(S02) providing a multi-phenyl monomer having a structure given in the following formula (II):
D2-Y-D2  (II)
wherein Y is


and D2 is halogen or hydroxyl group;
(S03) processing a nucleophilic polycondensation between the fluorine-containing monomer and the multi-phenyl monomer to form
a polymer of fluorine-containing poly(arylene ether)s having a structure given in the following formula (III):


wherein n is an integer greater than or equal to 2; and D2 is the hydroxyl group if D1 is the halogen group, or D2 is the
halogen group if D1 is the hydroxyl group; and

(S04) carrying out a sulfonation modification of the polymer of fluorine-containing poly(arylene ether)s to form a polymer
of fluorine-containing sulfonated poly(arylene ether)s having a molecular formula given in the following formula (1):


wherein j is an integer from 1 to 10.
