Abstract
In this study, synthesis and characterization of poly (p-tolyl methyl meyhacrylate) (PTMMA) polymer synthesized for the first time was studied. For this purpose, p-tolyl methyl methacrylate monomer was synthesized from the reaction of sodium methacrylate with p-tolyl chloride. The monomer was polymerized with free radical at 60 oC using benzoyl peroxide as the initiator. The structure of the resulting monomer and polymer was elucidated by IR, 1H-NMR, 13C-NMR techniques. The glass transition temperature was 65 oC, the solubility parameter was 8.69 (cal cm-3 ) 1/2 , the heterogeneity index was found to be 3.17 with GPC technique. The decomposition temperature was 205 oC and the density was determined as 1.12 gr cm-3 .
Özet
Bu çalışmada ilk kez sentezlenen poli (p-tolil metil metakrilat) ( PTMMA) polimerinin sentezi ve karakterizasyonuüzerinde çalışıldı. Bu amaçla sodyum metakrilatın p-totil klorürle reaksiyonundan p-tolil metil metakrilatmonomeri sentezlendi. Monomer, başlatıcı olarak benzoil peroksit kullanılarak 60 oC’de serbest radikallik yollapolimerleştirildi. Elde edilen monomer ve polimerin yapısı IR, 1H-NMR, 13C-NMR teknikleriyle aydınlatıldı.Polimerin camsı geçiş sıcaklığı 65 oC, çözünürlük parametresi 8.69 (cal cm-3)1/2, GPC tekniği ile heterojenlik indisi3.17 olarak bulundu. Bozunma sıcaklığı 205 oC ve yoğunluğu 1.12 gr cm-3 olarak belirlendi.
