초록

전분을 가소화시킨 thermoplastic starch(TPS)를 제조하고 이를 생분해성 지방족 폴리에스테르의 하나인 poly(butylene adipate-co-succinate) (PBAS)와 블렌드하였다. TPS의 조성 및 함량이 PBAS의 기계적 물성과 열적 성질 및 생분해도에 미치는 영향과 PBAS/TPS 블렌드의 발포특성을 관찰하였다. 소량의 TPS가 첨가됨에 따라 PBAS/TPS 블렌드의 인장강도, 신장률 및 인열강도는 급격히 저하되다가 함량이 증가할수록 감소폭이 둔화되는 경향을 보였다. TPS는 PBAS 블렌드의 결정화도와 열분해온도를 낮추었다. PBAS/TPS 블렌드에서 TPS의 함량이 20 phr일 때 최고의 발포배율을 가지는 발포체가 얻어졌으며, TPS 함량이 증가할수록 발포 배율은 낮아졌다.

Thermoplastic starch (TPS) was manufactured and blended with poly(butylene adipate-co-succinate) (PBAS), which is one of the most popular biodegradable aliphatic polyesters. The effects of the TPS contents on the mechanical properties, thermal characteristics, and biodegradability of PBAS/TPS blends were investigated. The foaming characteristics of those were also studied. With small amount of TPS, mechanical properties of the blends were largely deteriorated and the variations of them decreased with more addition of TPS. In addition, TPS decreased crystallinity and thermal decomposition temperature of PBAS. The PBAS/TPS foam, having maximum blowing ratio was obtained with 20 phr of TPS, and their blowing ratio decreased with the further increase of TPS.
