Product description

Poly-3-hydroxybutyrate-block-Polyethylene glycol-block-Poly-3-hydroxybutyrate,phb-b-peg-b-phb from ruixi.Amphiphilic Triblock Copolymer PHB-PEG-PHB.Amphiphilic triblock copolymers based on poly (beta-butyrolactone) (PHB) and polyethylene glycol (PEG) - poly (beta-butyrolactone) - poly (beta-butyrolactone) (PHB-PEG-PHB) can be prepared by anionic ring-opening polymerization of beta-butyrolactone (BL) in the presence of polyethylene glycol potassium salt macromolecular initiator and tetrahydrofuran as solvent. By adjusting the ratio of BL to polyethylene glycol potassium salt, various molecular weights can be prepared.
