摘要：
The activator regenerated by electron transfer atom transfer radical polymerization (ARGET ATRP) of octadecyl methacrylate (ODMA) was investigated. Effects of reaction temperature, ligand and reducing agent dosages on polymerization rate and reaction controllability were studied. The structure and properties of poly (octadecyl methacrylate) (PODMA) were studied by gel permeation chromatography (GPC), thermo gravimetric analyzer (TGA), differential scanning calorimetry (DSC), water contact angle (WCA) and atomic force microscopy (AFM). The results show that when the reaction temperature is between 75~95℃, ligand dosage is 10~20 times of catalyst molar dosage and reductant dosage is 5~20 times of catalyst molar dosage, octadecyl methacrylate can be polymerized via ARGET ATRP with good controllability and narrow molecular weight distribution. Moreover, such polymerization conditions are wider than that of short side chain methacrylate. This is mainly due to octadecyl methacrylate with long side chains has lower termination constants than those of short side chain methacrylate. The poly (octadecyl methacrylate) film has a water contact angle of 103°, which is mainly due to low surface tension of the long alkyl side chain and rough surface formed by side chain crystallization. © 2018, Editorial Board of "Journal of Chemical Engineering of Chinese Universities".
