Poly(DL-lactide) (PDLLA), MW 20-50K is a biodegradable polyester derived from DL-lactide. Its amorphous polymer structure and lower molecular weight provide good processability and controlled hydrolytic degradation specifically for drug delivery, controlled release, particle formulation, polymer formulation, and biomaterial research.
Key Features and Benefits
- Lower Molecular Weight: The 20-50K molecular weight range provides good processability for polymer formulation, fabrication, 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 lower 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, fibers, and other biodegradable polymer structures.
- Biomaterial Platform: Provides a biodegradable polymer matrix for drug delivery, controlled release, tissue engineering, and biomaterial development.
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 and composite systems.
- Tissue Engineering: Supports development of biodegradable polymer matrices for tissue engineering research.
- Polymer Processing: Suitable for 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.
