AbstractIn this study, hyperbranched polyether (HBP) with terminal hydroxyl was synthesized from tetrahydrofuran and glycidol by cationic open-loop polymerization and then modified by 2-phosphono-butane-1,2,4-tricarboxylic acid to introduce carboxyl and phosphorus to improve corrosion and scale inhibition. The structure of the products (HBPs) was determined by FTIR and H-1-NMR. The scale inhibition efficiency (E) of calcium carbonate and calcium sulfate reached 99.74 and 97.10% at a concentration of 20mg/L. X-ray diffraction and scanning electron microscopy were used to examine crystal type and morphology. The addition of scale inhibitors can inhibit the growth of the calcium scale crystal and destroy the crystal structure. The corrosion inhibition rate of HBPs can reach 72.98% when dosage was 150mg/L. Polarization curve showed that HBPs was a kind of mixed corrosion inhibitor. The adsorption of HBPs on the surface of carbon steel conformed to Langmuir adsorption, which formed physical adsorption film and inhibited the corrosion process. (c) 2019 Wiley Periodicals, Inc. J.
