A new approach to the synthesis of poly(arylene sulphide)s using masked bisthiophenols is presented. Bisthiophenols N-propylcarbamates can be purified easily by simple recrystallization and polycondensed directly with activated dihalide monomers in N-methylpyrrolidone in the presence of potassium bicarbonate.
