A Novel thermosensitive dendritic copolymer based on polyethylene glycol (PEG) and poly(N-isopropylacrylamide) (PNIPAm) with a cloud point (CP) around 36 ℃ was successfully synthesized by preparation of a dendritic polyol and followed by atom transfer radical polymerization (ATRP) of N-isopropylacrylamide. The dendritic copolymer was characterized using gel-permeation chromatography (GPC), FTIR and 1H-NMR spectroscopy. The self-association behavior of the copolymer in aqueous medium was investigated by dynamic light scattering (DLS) and transmission electron microscopy (TEM). These investigations confirmed that the dendritic copolymer showed different association behaviors at various temperatures.
