Synthesis of Phenacylmethacrylate: Its Characterization and Polymerization

Abstract

Phenacylmethacrylate (PAMA), a new monomer containing two carbonyl groups (Cdbnd]O), was obtained from phenacyl chloride and sodium methacrylate. The homopolymer of PAMA and its copolymer with styrene were prepared in dioxane by using benzoylperoxide (Bz₂O₂) as initiator. IR, ¹H-NMR and ¹³C-NMR techniques were used to identify the structure of the monomer and polymers. The density of monomer, homopolymer and copolymer were found to be 1.13; 1.35 and 1.10 gr/ml respectively. Also, limit viscosity numbers, solubility parameters, glass transition and decomposition temperatures of polymers were determined.
