Determination of Reactivity Ratios and Synthesis of Vinyl Pivalate-co-Maleic Anhydride Copolymer

In this study, VP-ko-MA copolymer was synthesized by studying at different feed ratios to determine the order of the copolymer structure and the ability to react with Vinyl Pivalate (VP) of maleic anhydride (MA). The structures of the synthesized VP-co-MA copolymers were elucidate by FT-IR and 1H-NMR spectroscopy and gel permeation chromatography. In addition, Cohesive Energy Density (KEY) values with titrimetric method and acid numbers as volumetric of the synthesized VP-co-MA copolymers were determined. The mole fractions of the monomers in the copolymer composition were determined by FT-IR and 1H-NMR spectroscopy and the reactivity ratios of VP-co-MA copolymer were determined by Fineman-Ross and Kelen-Tudos methods
