Özet

In this study, MA-S-MMA, MA-S-VA and MA-S-AP terpolymers have been synthesized in methyl ethyl ketone from methyl methacrylate (MMA), vinyl acetate (VA), allyl propionate (AP), styrene (S), and maleic anhydride (MA) monomers according to free radical polymerization in the presence of 2, 2-azobisisobutyronitrile (AIBN) as initiator at 70degreesC for 1 hour. The characterization of terpolymers has been done with the characteristic peak observed in FTIR. The viscosymetric analysis of solutions of terpolymers has been used to obtain information about molar mass of terpolymers. For thermomechanic analysis of terpolymers, the stress-strain and penetration-temperature curves of film samples have been recorded. A change at glass transition (Tg) values has been observed according to MA-S-MMA
