Abstract

image

Condensation reaction of poly(ethylene glycol) (PEG) with a carboxyl group at one chain end and hyperbranched polyamide (HBPA) with a hydroxyl group at the focal point was performed in the presence of condensation agent at ambient temperature, yielding PEG-b-HBPAs with defined molecular weight and very narrow molecular weight distribution. PEG-b-HBPA formed micelles in water.
