Abstract

Bu çalışmada öncelikle [2 – (p – brom
fenil)  1,3 – dioksalan  – 4 – il] metil akrilat monomeri (PBPhDMA)
sentezlendi. Sentezlenen monomer serbest radikalik yoldan polimerleştirildi.
Monomerin, Akrilonitril (AN) ve Stiren (St) ile kopolimerleri elde edildi.
Sentezlenen bütün yapılar FT-IR, ¹H-NMR teknikleri ile karakterize
edildi. Polimerlerin camsı geçiş sıcaklıkları DSC, termal kararlılıkları TGA
ile araştırıldı. Polimerlerin molekül ağırlıkları GPC ile belirlendi. Poli
(PBPhDMA – ko – AN)kopolimerine ait reaktivite oranları Kelen-Tudos ve Fineman
–Ross Yöntemleri kullanılarak bulundu.

Synthesis, Characterization and Physical Properties of Poly [2- (p-Bromophenyl) 1,3-Dioxalane-4-yl] Methyl Acrylate Copolymers

Abstract

In this work, Poly [2 – (p – bromophenyl) 
1,3 – dioxolane  – 4 – yl] methyl
acrylate(PBPhDMA) was first synthesized. The synthesized monomer was
polimerized by free radicalic polimerization. Copolymers of monomers,
acrylonitrile (AN) and styrene (St) were prepared. All the structures
synthesized were caharacterized by FT-IR, and ¹H-NMR
techniques.Thermal behaviors of polymers and glass transition temparatures were
measured by DSC and TGA. The polymers of average molecular weights were
measured by GPC. Poly (PBPhDMA – co – AN) reactivity ratios were calculated
according to the general copolymerization equation using Kelen-Tüdõs and
Finemann–Ross linearization methods.
