BP10976 OH-PDLA-COOR, Medium Molecular Weight Grades, IV: 1–3 dl/g, Mw: 90–480 kDa

OH-PDLA-COOR, Medium Molecular Weight Grades, IV: 1–3 dl/g, Mw: 90–480 kDa Description

OH-PDLA-COOR (Medium Mw Grade) is an end-functionalised poly(D-lactic acid) with a molecular weight range of 90–480 kDa and intrinsic viscosity between 1–3 dl/g. Its D-configured backbone enables the formation of high-performance stereocomplexes with PLLA, while the medium chain length provides an optimal balance of mechanical strength, processability, and controllable degradation. The terminal hydroxyl and ester groups offer dual reactivity for further chemical modification and improved interfacial adhesion, making it a versatile material for designing durable yet biodegradable structures and functional systems.
