Title:
Polymerization method of polyarylene sulfide
Document Type and Number:
Japanese Patent JP6316462
Kind Code:
B2
Abstract:
A method for preparing a polyarylene sulfide includes reacting a methyl 4-(arylthio)aryl sulfoxide compound with sulfuric acid, methanesulfonic acid, benzenesulfonic acid, p -toluenesulfonic acid or trifluoromethanesulfonic acid to obtain a polysulfonium intermediate; and demethylating the polysulfonium intermediate to obtain a polyarylene sulfide, wherein the polysulfonium intermediate is demethylated with aqueous HCl, HBr, or HI.
