BP10972 OH-PLLA-COOH, Low Molecular Weight Grades, IV ≤ 1 dl/g, Mw ≤ 90 kDa

OH-PLLA-COOH, Low Molecular Weight Grades, IV ≤ 1 dl/g, Mw ≤ 90 kDa Description

OH-PLLA-COOH (Low Mw Grade) is an end-functionalised biodegradable polymer characterised by its short polymer chains and hydroxyl and carboxyl groups at each chain end. With a molecular weight ≤ 90 kDa and intrinsic viscosity ≤ 1 dl/g, it offers faster degradation profiles, good solubility, and lower processing viscosity. The dual end-group structure provides a versatile platform for chemical modification, ensuring its utility as a precursor or additive in designing functional and degradable materials.

OH-PLLA-COOH, Low Molecular Weight Grades, IV ≤ 1 dl/g, Mw ≤ 90 kDa Applications

1.         Polymer Synthesis & Modification
   - Polymer Building Block: Serves as a macro-initiator or chain segment for synthesising well-defined block or graft copolymers.
   - Functional Additive: Acts as a degradation modifier, plasticiser, or reactive additive in coatings, adhesives, or composite systems, improving compatibility or introducing degradation sites via its end groups.

2.         Functional Materials & Formulations
   - Degradable Coatings & Films: Used in preparing short-term protective coatings, packaging films, or degradable barrier layers, where its rapid degradation aligns with environmental requirements.
