Bu çalışmada, Maleik Anhidrit (MA) ve vinil Pivalat (VP)’ın birbirleri ile reaksiyona girebilme yeteneğinin ve kopolimer yapısındaki dizilimlerinin belirlenebilmesi için VP-ko-MA kopolimeri farklı besleme oranlarında çalışılarak sentezlenmiştir. Sentezlenen VP-ko-MA kopolimer yapısının aydınlatılabilmesi için kızılötesi (FT-IR) ve nükleer manyetik rezonans spektroskopilerinden (¹H-NMR) ve jel geçirgenlik kromotografisinden yararlanılmıştır. Ayrıca sentezlemiş olan VP-ko-MA kopolimerinin volumetrik olarak asit sayıları, titrimetrik yöntemle Kohezif Enerji Yoğunluğu (KEY) değerleri bulunmuştur. Kopolimer bileşimindeki monomerlerin mol fraksiyonlarının FT-IR ve ¹H-NMR spektroskopisi yardımıyla tayini yapılmış olup Fineman-Ross ve Kelen-Tüdos metotları yardımıyla da VP-ko-MA kopolimerinin reaktivite oranları belirlenmiştir.

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

Öz

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.
