Abstract
Polyesteramide(PEA) elastomer, whose soft segment was poly(butylene adipate) and whose hard segment was polyamide with some aromaticity, was partially miscible with poly(butylene terephthalate) (PET). The crystallization of PET was enhanced when small quantity of PEA elastomer was blended with PET. In PET/Nylon 6 blends, the PEA elastomer was preferentially dissolved into Nylon 6 phase, and the compatibility between PET phase and Nylon 6 phase was improved by the addition of PEA elastomer.

Soft segment가 poly(butylene adipate)이고 hard segment가 aromaticity를 갖는 폴리아미드인 polyesteramide (PEA) 탄성체는 poly(butylene terephthalate) (PBT)와 부분적 상용성을 가졌으며, PBT의 결정화는 소량의 PEA 탄성체의 첨가에 의해 촉진되었다. PBT/Nylon 6블렌드에 PEA 탄성체를 첨가하는 경우 부분적인 상용화 효과가 관찰되었으며, 이는 PEA 탄성체가 Nylon 6 영역으로 우선적으로 녹아들어가면서 Nylon 6 영역과 PBT 영역의 혼화성을 증대시키기 때문으로 생각되었다.
