| Abstract: | Methylacrylic acid polyethylene glycol single methyl ether(1200)ester(MPEGMAA) was synthesized by direct esterification of methylacrylic acid(MAA) and polyethylene glycol single methyl ether(MPEG) as raw materials in the presence of p-toluene sulfonic acid as catalyst,hydroquinone as inhibitor and using inert gas as water-carrying agent.The influence of molar ratio of monomer,dosage of inhibitor,dosage of catalyst and reaction time on the esterification were investigated.Double-bond stretching vibration ban... |
