BP10970 OH-PLLA-OH, Medium Molecular Weight Grades, IV: 1–3 dl/g, Mw: 90–480 kDa

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

OH-PLLA-OH (Medium Mw Grade) is an end-functionalised biodegradable polymer characterised by its intermediate chain length and symmetric hydroxyl termination. With a defined molecular weight range (90–480 kDa) and intrinsic viscosity (1–3 dl/g), it offers an optimal balance of mechanical properties, processability, and controlled degradation. The dual hydroxyl end groups provide enhanced reactivity for chemical modification, making it a versatile platform for synthesising tailored copolymers and formulating functional materials.
