BP10978 OH-PDLA-OH, Low Molecular Weight Grades, IV ≤ 1 dl/g, Mw ≤ 90 kDa

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

OH-PDLA-OH (Low Mw Grade) is a symmetrical, dihydroxy-terminated poly(D-lactic acid) in powder form, with a molecular weight ≤ 90 kDa and intrinsic viscosity ≤ 1 dl/g. Its dual hydroxyl end groups provide a versatile and reactive platform for chemical modification, chain extension, and network formation. Combined with the D-configured backbone that enables stereocomplexation, this material serves as a telechelic building block for constructing well-defined, high-performance biodegradable polymers, networks, and functional composites with tailored properties.

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

1.         Polymer Synthesis & Advanced Materials
- Telechelic Macroinitiator/Building Block: Utilised for synthesising well-defined block copolymers, biodegradable polyurethanes, and cross-linked networks via reactions with diacids, diisocyanates, or other bifunctional agents.
- Stereocomplex Precursor: Serves as a reactive diol component for preparing stereocomplex-enhanced materials with PLLA-based counterparts, yielding products with enhanced thermal and mechanical properties.

2.         Electronics & Functional Coatings
- Biodegradable Encapsulant/Linker: Applied in flexible and transient electronics as a degradable coating or adhesive layer, where its dual reactivity ensures strong interfacial bonding and controlled disintegration.
