Claim of US Patent No. 9,209,472

1. A manufacturing method for a polymer of sulfonated poly(arylene ether)s, comprising steps of:
(S01) providing a multi-phenyl glycol monomer which has the structure given in the following formula (I):
wherein X is

(S02) providing a multi-phenyl dihalo monomer having the structure given in the following formula (II):
Ha-Y-Ha  (II)
wherein Ha is selected from fluorine (F), chlorine (Cl) or bromine (Br), Y is selected from

(S03) forming a polymer of poly(arylene ether)s by a nucleophilic displacement reaction from the multi-phenyl glycol monomer
and the multi-phenyl dihalo monomer, which has the structure given in the following formula (III):

Wherein n is an integer greater than or equal to 2; and
(S04) carrying out a sulfonation modification of the polymer of the poly(arylene ether)s to form a polymer of sulfonated poly(arylene
ether)s having the structure given in the following formula (IV):

wherein i is an integer between 1 and 10.
