1) 货号：D-C-5k5k; （2) 品名: PEG-PCL, PEG MW 5000 & PCL MW 5000 ; 聚乙二醇-b-聚己内酯, 聚乙二醇 MW 5000 & 聚己内酯 MW 5000 ; 3) 规格: 500mg/1g/5g; 4) 描述: PEG-PCL is an amphiphilic AB diblock copolymer consisting of a hydrophilic block polyethylene glycol (PEG) or polyethylene oxide (PEO) and a hydrophobic block polycaprolactone (PCL). The PEG polymer is capped a methyl ether group, and the hydrophobic block terminates with a hydroxyl group. Biocompatible PEGylated copolymers with biodegradable polyester segments can be used to prepare core-shell micelles, nanoparticles and microspheres. The hydrolytic degradability of the polyester block depends on the molecular weight and the spacer between ester groups (lactide, glycotide or caprolactone). PEG-PCL with other MWs is also offered.
