Abstract A series of hyperbranched linear surfactants (HLS) was prepared by using oleic acid modifying the first generation hydroxyl‐terminated hyperbranched polymer (HBP‐1), which was obtained through a step synthesis method using trimethylolpropane and N,N ‐dihydroxyethyl dodecylamine ‐3‐amine‐methyl propionate (AB 2 ‐type monomer). AB 2 —type monomer was obtained through the Michael addition reaction of methyl acrylate and diethanol amine. Single‐factor experiments were conducted to investigate the influences of reaction conditions such as temperature, oleic acid dosage, and reaction time on the synthesis of HLS. Results indicate that the optimal temperature and time of the esterification reaction were 130 °C and 3 h, respectively. The structures of HLS were characterized by Fourier transform infrared spectrophotometry (FT‐IR) and the results indicate that HBP‐1 had been successfully modified by oleic acid. Furthermore, the surface tension and the critical micelle concentration (CMC) of the HLS solution show that HLS can significantly reduce the surface tension of water.
