PLGA-di-acid, MW 40K

PLGA-di-acid, MW 40K represents an ultra-high molecular weight linear biodegradable polyester functionalized with dual terminal carboxylic acid groups. Synthesized via copolymerization of D,L-lactide and glycolide monomers, this polymer supports all standard LA/GA ratios including 50:50, 65:35, 75:25, and 85:15, alongside fully customized ratio configurations to meet high-standard biomedical research requirements. Owning an ultra-long molecular chain structure, this 40K grade delivers exceptional mechanical toughness, superior structural rigidity, and an extremely prolonged biodegradation cycle compared with lower molecular weight PLGA-diacid derivatives. Despite its high molecular weight, the symmetric terminal carboxyl groups retain effective chemical reactivity, enabling precise amide conjugation, high-density crosslinking, and high-performance block copolymer synthesis. Featuring excellent biocompatibility and fully metabolizable degradation byproducts, this polymer is uniquely tailored for the fabrication of ultra-long sustained-release delivery systems, high-strength biodegradable tissue engineering scaffolds, and highly stable polymeric biomaterials that require long-term in-situ structural retention.
