Biyobozunur ürünler, sentetik polimerlerin kullanımından kaynaklanan atıkların azaltılmasında önemli bir çözüm olarak kabul edilmektedir. Termoplastik nişasta (TPS), biyolojik olarak parçalanabilen ürünlerin hazırlanmasında başarısı ve düşük maliyeti ile öne çıkmaktadır. Biyobozunur polimerik ürünlerin düşük mekanik ve fiziksel özelliklerini iyileştirmek için, umut verici bir çözüm olan ve çalışmamızın hedefi olarak eş-sürekli formdaki morfoloji seçilmiştir. Bu amaçla nişasta ve çeşitli plastikleştiriciler kullanılarak eriyik işleme yöntemiyle termoplastik nişasta (TPS) numuneleri hazırlanmıştır. TPS numuneleri morfolojik, reolojik ve termal özellikler açısından incelenmiştir. Elde edilen sonuçlara göre polietilen (PE) ile hazırlanacak polimer karışımlarında eş sürekli morfolojinin elde edilmesini sağlayacak uygun TPS örneği belirlenmiştir. Seçilen TPS numunesi ve PE farklı bileşimlerde olacak şekilde polimer karışımları eriyik işleme yöntemiyle hazırlanmıştır. TPS/PE polimer karışımları mekanik, reolojik, morfolojik ve termal özellikler açısından incelenmiş ve TPS kompozisyonu yüksek ve eş sürekli faz morfolojisine sahip numunelerin hazırlanması için en uygun yöntem ve parametreler belirlenmiştir.
