Abstract

Polystyrene is one of the most widely used synthetic polymer in daily life. In this study, the chemical modification of polystyrenes which have different molecular weight, with maleic anhydride and acetic anhydride in the presence of catalyst (BF3∙O(C2H5)2 ) and in the optimum conditions which have been found in previous studies, has been done and some polyfunctional groups (CH3CO- and -CH2-CH=CH-COOH) containing polystyrenes have been manufactured. Various physicomechanical properties as tensile strengths, softening temperatures and hardness determination of modified polystyrenes have been researched. Finally, modified polystyrenes have been compared depending on functional groups

Özet

Polistiren, günlük hayatta en yaygın kullanılan sentetik polimerlerden biridir. Bu çalışmada değişik molekül ağırlıklı polistirenlerin asetik ve maleik anhidritlerle (BF3∙O(C2H5)2) katalizörlüğünde daha önce bulunmuş optimum reaksiyon şartlarında kimyasal modifikasyonu gerçekleştirilmiş ve yapısında (CH3CO- ve -CH2-CH=CH-COOH) grupları içeren değişik molekül ağırlıklı modifiye polistirenler sentezlenmiştir. Elde edilen modifiye polistirenlerin kopma mukavemetleri, yumuşama sıcaklıkları ve sertlik tayinleri gibi çeşitli fiziko-mekanik özellikleri incelenmiştir. Sonuçta elde edilen modifiye polistirenlere bağlanan fonksiyonel grupların özelliklerine bağlı olarak kıyaslamalar yapılmıştır.
