Product name: Polymer PEG derivative PLLA-ACID, MW: 20000
plla:Indicates a copolymer that contains a reference to L-lactic acid (poly-L-lactide). PLLA is a copolymer of poly-L-lactic acid, which is usually polymerized from L-lactide monomer. L-lactic acid is the L-isomer of lactic acid, whereas PLLA is a polymer consisting of L-lactic acid monomers. PLLA is a biodegradable polymer that is widely used in the medical field, such as biodegradable implant materials, sutures, and drug delivery systems.
acid:This may indicate an acid, but it is not specified which acid it is. The introduction of acids may affect aspects such as surface properties, biocompatibility, etc. of polymers.
Overall, PLLA-ACID is a polymer with a molecular weight of 20,000 consisting of a poly-L-lactic acid copolymer and an acid. Such polymers may have some applications in the medical field, such as for the preparation of degradable implant materials, drug delivery systems, etc. However, the specific application and properties depend on the specific design of the acid and copolymer chosen.
Poly-L-lactide (PLLA) is a biodegradable polymer formed by the polymerization of L-lactide monomer. L-lactic acid is the L-isomer of lactic acid, whereas PLLA is a polymer consisting of L-lactic acid monomers.
Here are some of the properties and applications of L-polylactic acid (PLLA):
Biodegradability:PLLA is a biodegradable polymer that can be gradually degraded into lactate monomers in the body through hydrolysis, which is eventually metabolized and excreted. This property makes PLLA particularly suitable for medical applications that require temporary support and fade away.
Medical Applications:PLLA is widely used in the medical field, including the preparation of biodegradable implant materials, sutures, stents, etc. For example, PLLA scaffolds can be used to support tissue engineering and promote tissue regeneration.
Drug Delivery Systems:Due to its degradable properties, PLLA is also commonly used in the preparation of drug delivery systems. The drug can be embedded in the PLLA matrix and released as the PLLA is degraded, enabling long-term drug delivery.
Plasticity and processability:PLLA has good plasticity and processability, and products of various shapes and structures can be prepared by traditional plastic processing methods such as thermoforming, injection molding, etc.
Biocompatibility:PLLA has good biocompatibility and less irritation to surrounding tissues, reducing inflammation and rejection caused by implants.
Overall, L-polylactic acid (PLLA) is a versatile biodegradable polymer whose properties make it widely used in the medical and biomedical fields.
