SYNTHESIS OF PHENACYLMETHACRYLATE - ITS CHARACTERIZATION AND POLYMERIZATION

Phenacylmethacrylate (PAMA), a new monomer containing two carbonyl gro ups (C=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 (Bz(2)O(2)) as initiator. IR, H-1 -NMR and C-13-NMR techniques were used to identify the structure of th e monomer and polymers. The density of monomer, homopolymer and copoly mer were found to be 1.13; 1.35 and 1.10 gr/ml respectively. Also, lim it viscosity numbers, solubility parameters, glass transition and deco mposition temperatures of polymers were determined.
