BP10973 OH-PLLA-COOH, Medium Molecular Weight Grades, IV: 1–3 dl/g, Mw: 90–480 kDa

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

OH-PLLA-COOH (Medium Mw Grade) is an end-functionalised biodegradable polymer with a molecular weight range of 90–480 kDa and an intrinsic viscosity of 1–3 dl/g. Featuring both hydroxyl and carboxyl groups at the polymer chain ends, it provides balanced mechanical properties, controllable degradation profiles, and excellent processing versatility. The moderate chain length achieves an optimal balance between structural strength and processability, making it suitable for applications that require both mechanical integrity and functional performance. It serves as an ideal choice for designing sustainable materials.

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

1.         Polymer Synthesis & Modification
   - Polymer Building Block: Serves as a reactive intermediate for synthesising higher molecular weight polymers, block copolymers, and cross-linked networks.
   - Functional Additive: Acts as a compatibiliser, toughness enhancer, or degradation modifier in polymer blends and composite systems.

2.         Functional Materials & Formulations
   - Biomedical Devices: Used in the fabrication of medium-to-long-term implants, surgical sutures, and orthopaedic fixation devices where balanced degradation and mechanical strength are required.
   - Tissue Engineering Scaffolds: Employed in constructing three-dimensional scaffolds that provide structural support for cell growth while gradually degrading as new tissue forms.
   - Controlled Release Systems: Serves as a matrix material for sustained drug delivery applications requiring longer release profiles than low molecular weight grades can provide.
   - Biodegradable Packaging: Used in the production of durable yet compostable packaging materials that maintain integrity during use while degrading under appropriate environmental conditions.
