Preparation of poly(phenylene vinylene) from cycloalkylene sulfonium salt monomers and polymers

Abstract

Abstract Two new types of p ‐xylene bis‐sulfonium chloride monomers were prepared from cycloalkylene sulfides. The polymerization characteristics of these monomers to form poly( p ‐xylene sulfonium chlorides), and the thermal elimination reactions of their polymers to poly( p ‐phenylene vinylene), were compared with those of two monomers prepared from dialkyl sulfides. The cycloalkylene sulfonium chloride monomer polymerized to higher yields and to higher molecular weight polymers, which showed more efficient elimination reactions.
