The Thermal and Rheological properties of Linear and Star-shaped Poly(L-lactic acid)

선형과 스타형 Poly(L-lactic acid)의 열적, 유변학적 특성

Poly(lactic acid) is a thermoplastic and biodegradable polymer[1-3]. It has a wide range of application in medical fields such as sutures, screws for bone fractures and drug delivery systems. It has additional potential in other fields like agriculture and packaging. In recent years, there has been an increased interest in star-shaped polymers because they have a higher segment density within the distance of its radius of rotation than linear polymers have under the same conditions.[4] (omitted)
