Abstract

Abstract : New amine functional sulfur prepolymers were synthesized from inexpensive poly(sulfur‐ random ‐styrene) and 1, 3‐ meta ‐phenylenediamine (PDA) via a proposed electrophilic aromatic substitution (SE Ar) reaction. These chalcogenide hybrid inorganic/organic polymer resins show improved solubility in organic solvents. The aromatic amine functional groups were utilized to react with epoxides on polyhedral oligomeric silsesquioxanes through post‐polymerization modification which resulted in crosslinked sulfur polymers.
