On pressure and temperature affacted shear viscosity behaviour of poly(lactid) acid melt
Original language description
Rheological properties of extrusion grade of poly(lactid) acid (PLA) as one of the most important bio-base sustainable polymer potentially applicable for medical applications was studied. Shear flow behavior of PLA melt was determined using capillary rheometer modified by backpressure device directly connected to the main rheological apparatus. The device employed increases pressure actuating on polymer melt stream in capillary reservoir through restricting valve resulting in increase of melt viscosity.The temperature and pressure coefficient was obtained through the viscosity data fitting with Carreau-Yasuda model. The study indicated that shear viscosity of this PLA is strongly influent by temperature and pressure.
