BP10960 OH-PDLLA-OH, Low Molecular Weight Grades (IV ≤ 0.18 dl/g, Mw ≤ 15 kDa)

OH-PDLLA-OH, Low Molecular Weight Grades Description

OH-PDLLA-OH (Low Mw Grade) is a short-chain, difunctional biodegradable polymer terminated with hydroxyl groups at both ends. Its low molecular weight (≤ 15 kDa) and intrinsic viscosity (≤ 0.18 dl/g) are engineered for applications requiring high reactivity, ease of chemical modification, and rapid processing. This grade serves as a versatile platform for constructing segmented copolymers, modifying material surfaces, or formulating rapidly degradable binders and coatings.

OH-PDLLA-OH, Low Molecular Weight Grades Applications

1.         Polymer Synthesis & Modification
- Block Copolymer Synthesis: Act as a difunctional initiator for ring-opening polymerisation of lactones (e.g., ε-caprolactone, glycolide) to create tailored ABA-type triblock copolymers with specific properties.
- Polyurethane/Polyester Prepolymer: React with diisocyanates or diacids/diesters to form biodegradable polyurethane or polyester segments for elastomers, adhesives, or coatings.

2.         Functional Coatings & Resins
- Cross-linking Agent: Incorporate into thermosetting resin formulations (e.g., with polyisocyanates or anhydrides) to introduce hydrolyzable linkages, creating degradable protective coatings or composites.
- Surface Modification: Graft onto material surfaces to introduce a hydrophilic, hydroxyl-rich interface for improved adhesion or subsequent chemical grafting.

3.         Specialty Binders & Temporary Materials
- Fugitive Binder: Use as a binder in ceramic or metal powder shaping processes, which cleanly decomposes during thermal treatment.
- Rapid-Release Matrix: Formulate temporary encapsulation systems for agrochemicals, dyes, or catalysts where quick and complete release is required.

Additional Information

This difunctional low molecular weight grade is a powerful chemical building block due to its precisely defined architecture. The presence of two hydroxyl groups distinguishes it from monofunctional versions, enabling linear chain extension or network formation. Its rapid degradation profile is an integral feature for designing transient functional materials. SAM provides technical support on reaction conditions and formulation strategies to leverage this polymer's full potential in advanced material projects.
