Poly(L-lactide)(PLLA), MW 60-100K is a biodegradable polyester derived from L-lactide. Its stereoregular polymer structure provides crystallinity, mechanical properties, processability, and controlled degradation, making it especially suitable for drug delivery, biomaterials, scaffold fabrication, tissue engineering, and polymer research.
Key Features and Benefits
- Intermediate Molecular Weight: The 60-100K molecular weight range provides a practical balance of mechanical properties, polymer processability, and degradation behavior.
- Biodegradable Polyester: PLLA undergoes hydrolytic degradation of its ester backbone, producing lower-molecular-weight degradation products.
- Stereoregular Polymer Structure: The L-lactide-derived structure promotes crystallinity and specifically provides useful thermal and mechanical properties.
- Mechanical Properties: PLLA provides structural integrity for biodegradable polymer matrices while offering easier processing than very high-molecular-weight grades.
- Controlled Degradation: The semicrystalline polyester structure supports gradual hydrolytic degradation for biomaterial and controlled-release applications.
- Processable Polymer: Supports fabrication into films, fibers, particles, porous scaffolds, and other polymer structures using appropriate processing methods.
- Biomaterial Platform: Provides an especially versatile biodegradable polymer matrix for drug delivery, tissue engineering, controlled release, and biomaterial development.
Applications
- Drug Delivery: Supports development of biodegradable particles, matrices, and controlled-release drug-delivery systems.
- Controlled Release: Provides a biodegradable polymer matrix for sustained-release formulation research.
- Tissue Engineering: Supports fabrication of biodegradable scaffolds and matrices for tissue engineering research.
- Scaffold Fabrication: Suitable for porous scaffolds, fibers, membranes, films, and other polymer structures.
- Electrospinning: Supports preparation of PLLA fibers and fibrous matrices for biomaterial research.
- Polymer Processing: Supports research involving solvent casting, extrusion, molding, and other compatible polymer-processing techniques.
- Biomaterial Research: Supports development of biodegradable materials, polymer composites, coatings, and related biomaterial systems.
Storage and Handling
- Storage: Store in a tightly sealed container under cool, dry conditions. For long-term storage, keep the material protected from moisture and excessive heat.
- Handling: Protect from moisture because hydrolysis can reduce polymer molecular weight. Dry the polymer appropriately before melt processing or other moisture-sensitive applications.
