Poly(DL-lactide) (PDLLA), MW 10-20K is a low-molecular-weight biodegradable polyester derived from DL-lactide. Its amorphous polymer structure provides good processability and hydrolytic degradability specifically for drug delivery, controlled release, particle formulation, polymer formulation, and biomaterial research.
Key Features and Benefits
- Low Molecular Weight: The 10-20K molecular weight range provides good processability for polymer formulation, particle preparation, and controlled-release research.
- Biodegradable Polyester: PDLLA contains hydrolyzable ester linkages that specifically support gradual polymer degradation under appropriate conditions.
- Amorphous Polymer Structure: The random distribution of D- and L-lactide units limits crystallization, giving PDLLA a predominantly amorphous structure.
- Good Processability: The low molecular weight facilitates polymer dissolution, formulation, and processing compared with higher-molecular-weight PDLLA grades.
- Controlled Degradation: The amorphous polyester structure supports hydrolytic degradation specifically for controlled-release and biodegradable material applications.
- Versatile Polymer Platform: Supports preparation of particles, films, coatings, polymer matrices, and other biodegradable polymer structures.
- Formulation Flexibility: The lower molecular weight makes this grade useful for research involving polymer blends, drug-loaded matrices, and particle-based formulations.
Applications
- Drug Delivery: Supports development of biodegradable particles, polymer matrices, and drug-delivery systems.
- Controlled Release: Provides a biodegradable polymer matrix for sustained and controlled-release formulation research.
- Particle Formulation: Suitable for research involving PDLLA-based microparticles, nanoparticles, and related delivery systems.
- Polymer Formulation: Supports development of biodegradable polymer formulations, blends, and composite systems.
- Coatings and Films: Suitable for preparation of biodegradable coatings, thin films, and related polymer structures.
- Polymer Processing: Supports research involving solvent casting, coating, molding, and other compatible processing techniques.
- Biomaterial Research: Supports development of biodegradable polymer systems, composites, coatings, and related biomaterials.
Storage and Handling
- Storage: Store in a tightly sealed container under cool, dry conditions. Protect from moisture and excessive heat during long-term storage.
- Handling: Protect from moisture because hydrolysis can reduce polymer molecular weight. Dry the polymer appropriately before melt processing or other moisture-sensitive applications.
This product provides a low-molecular-weight, amorphous biodegradable polymer platform with good processability and controlled degradation. It specifically supports drug delivery, controlled release, particle formulation, polymer formulation, and biomaterial research.
