In this paper, a series of linear-dendritic block copolymers allyloxy poly(ethylene glycol) polyglycerol (APEG-PG-(OH)(n)) copolymer, was synthesized by anionic polymerization of glycerol using allyloxy poly(ethylene glycol) (APEG). The polymers were characterized by FT-IR and H-1 NMR. The polymers were tested as novel environment-friendly inhibitors for industrial cooling water circulation. The performance of AA/APEG-PG-(OH)(n) on inhibition of calcium phosphate and calcium carbonate precipitation was studied by static scale inhibition tests. It was shown that AA/APEG-PG-(OH)(n) exhibited excellent ability to control inorganic minerals, with approximately 99% calcium phosphate inhibition and 85% calcium carbonate inhibition at levels of 4 and 10 mg/L AA/APEG-PG-(OH)(n), respectively. The effect on formation of calcium phosphate and calcium carbonate was investigated with combination of scanning electronic microscopy (SEM), transmission electron microscopy (TEM), X-ray powder diffraction (XRD) analysis, respectively.
