By taking advantage of competing side reactions, controlled synthesis of a series of homo- and co-polymerized hyperbranched polyethers (HBPEs) is demonstrated using AB2 monomers of different spacer lengths. This reacting system shows good controllability and scalability. More importantly, the degree of branching is found to be insensitive to the molecular weight and spacer length in monomers. Thus
