Thermomechanical Investigation of the Effect of Maleic Anhydride Containing Copolymer on Polystyrene/Polyvinylchloride Blends

Öz

Polystyrene (PS) and Polyvinylchloride (PVC) are two widely used polymers that do not form compatible mixtures with each other. By adding Maleic anhydride/Styrene (MAS) copolymer to the two polymers, the effect on miscibility was investigated thermomechanically. Stress-strain analysis of the mixtures was performed. Thermomechanical processes were completed by creating temperature-strain and temperature-logE curves from the stress-strain curves obtained under increasing load and temperature. By processing these data, Modulus of Elasticity (E), coefficient of thermal elongation (CTE) and Glass transition temperatures (Tg) of the mixtures were calculated. It was observed that MAS copolymer added to PS/PVC mixtures as a compatibilizer increased the thermomechanical strength and was a good compatibilizer as the mixtures had a single glass transition temperature.

Polistiren/Polivinilklorür Karışımlarına Maleik Anhidrit İçeren Kopolimer Etkisinin Termomekanik İncelenmesi

Öz

Polistiren (PS) ve Polivinilklorür (PVC) birbirleri ile uyumlu karışım oluşturmayan yaygın kullanıma sahip iki önemli polimerdir. İki polimere Maleik anhidrit/Stiren (MAS) kopolimeri eklenerek karışabilirliğe olan etkisi termomekanik olarak incelendi. Karışımların gerilim-gerinim analizi yapıldı. Artan yük ve sıcaklık altında elde edilen gerilim-gerinim eğrilerinden, sıcaklık-gerinim, ve sıcaklık-logE eğrileri de oluşturularak termomekanik işlemler tamamlandı. Bu verilerin işlenmesiyle karışımlara ait Elastisite Modülü (E), Isısal uzama katsayısı (IUKS) ve Camsı geçiş sıcaklıkları (Tg) hesaplandı. PS/PVC karışımlarına uyumlaştırıcı olarak eklenen MAS kopolimerinin termomekanik dayanımı arttırdığı ve karışımların tek bir camsı geçiş sıcaklığına sahip olmasıyla iyi bir uyumlaştırıcı olduğu görüldü.
