Molecular and Bulk Characterization of PLA and PLGA Samples Using Multi-Detector GPC and Rheometry
Application Note Jan 29, 2018
This application note uses two Malvern technologies to explore the relationship between the molecular and bulk properties of PLA and PLGA. Multi-detector GPC is used to measure molecular weight and intrinsic viscosity (which is dependent on copolymer composition), while rotational rheology is used to study melt-viscosity. The two results are then compared to study which molecular properties best correlate with melt-viscosity.
