Abstract:

 


Copolymers of five percentages (10, 30, 50, 70, 90) were synthesized from 2-acetyl benzofuran methacrylate (ABM) and styrene (St) in the presence of benzoyl peroxide (Bz2O2) by free radicals. The polymers were dissolved in dioxane and precipitated in petroleum ether. Copolymers were characterized by elemental analysis, 1H-NMR, FT-IR, DSC, TGA and GPC. Itwas observed that as the ABM ratio increased in the poly(ABM-co-St) copolymer series, the degradation temperature decreased and as the ABM ratio increased, the glass transitiontemperature also increased (127-136 °C). The monomer reactivity ratios in the copolymer were found to be between 0 and 1 at r1.r2 values from Kelen Tudos and Fineman Ross methods. The activation energies of the copolymers were found in the Arrhenius equation (23-30 Joules).

2-Asetil benzofuran metakrilat (ABM) ve stiren (St) benzoil peroksit (Bz2O2) varlığında beş farklı yüzde oranlarında % (10, 30 50, 70, 90) kopolimerler serbest radikallik yoldan sentezlendi.Polimerler, dioksanda çözülüp petrol eterinde çöktürüldü. Kopolimerler, elementel analiz, 1HNMR, FT-IR, DSC ve TGA, GPC ile karakterize edildi. Poli(ABM-ko-St) kopolimer serilerindeABM oranı arttıkça bozunma sıcaklığının düştüğü, camsı geçiş sıcaklıkları ABM oranı artıkça (127-136 0C) yükseldiği gözlendi. Kopolimerdeki monomer reaktiflik oranları. Kelen Tudos ve Fineman Ross metodlarından r1.r2 değeri 0 ve 1 aralığında bulundu. Kopolimerlerin aktivasyon enerjileri Arrhenius denkleminden (23-30 Joule) bulundu.
