PDLLA-PEG-PDLLA Diacrylate

$360.00

PLLA-PEG-Alkyne (Poly(L-lactide)-b-Polyethylene Glycol-Alkyne) is a tin-free, biodegradable amphiphilic block copolymer consisting of poly(L-lactide) (PLLA) and polyethylene glycol (PEG) terminated with an alkyne group. The hydrophobic PLLA segment enables drug encapsulation and nanoparticle formation, while the hydrophilic PEG segment improves aqueous solubility and biocompatibility. The terminal alkyne group provides a versatile handle for click chemistry conjugation with azide-containing molecules, making PLLA-PEG-Alkyne ideal for targeted drug delivery, nanoparticle functionalization, and biomaterials research.

Description

General Description

PDLLA-PEG-PDLLA Diacrylate is a biodegradable triblock copolymer designed for the preparation of photocrosslinkable hydrogels and bioresorbable polymer networks. The hydrophobic PDLLA segments contribute biodegradability and mechanical strength, while the PEG segment provides hydrophilicity, flexibility, and biocompatibility.

The terminal acrylate groups readily undergo free-radical polymerization and photopolymerization in the presence of suitable initiators, allowing formation of crosslinked hydrogel structures under mild conditions. PDLLA-PEG-PDLLA Diacrylate is widely used in injectable hydrogels, tissue scaffolds, cell encapsulation, controlled drug release systems, and regenerative medicine research.
