Product name: Polymer PEG derivative PDLLA-ACID, MW: 5000
pdlla:Indicates a copolymer that contains a reference to poly-L-lactic acid (Poly-D, L-lactide). PDLLA is a copolymer of poly-L-lactic acid, which is typically composed of L-lactate and D-lactide monomers. This copolymer is a biodegradable polymer that is widely used in medical applications such as biodegradable implants, 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, PDLLA-ACID is a polymer with a molecular weight of 5000 consisting of a poly-L-lactic acid copolymer and some 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-D, L-lactide, or PDLLA, is a copolymer formed by the polymerization of L-lactide monomer. L-lactic acid is a chiral, enantiomeric lactic acid, while poly-d, l-lactide is a mixture of monomers of both L-lactate and d-lactide.
PDLLA copolymer is a biodegradable polymer whose degradation product is lactic acid, which can eventually be metabolized and excreted by living organisms. This property makes PDLLA widely used in the medical and biomedical fields, including but not limited to the following:
Implant Materials:PDLLA can be used to prepare biodegradable implant materials such as sutures, bone repair stents, absorbent sutures, etc. While these materials provide support at first, they gradually degrade over time and are no longer present in the body.
Drug Delivery Systems:PDLLA is also used in the preparation of drug delivery systems, in which the drug is embedded in a polymer matrix. As PDLLA is degraded, the drug is gradually released, allowing for long-term drug delivery.
Tissue Engineering:PDLLA has been applied to support and guide the development of tissue engineering, for example for the construction of 3D scaffolds and models to promote cell growth and tissue regeneration.
The properties and rate of degradation of PDLLA copolymers can be controlled by adjusting the ratio of L-lactic acid to D-lactic acid and the molecular weight to meet the needs of specific applications.
