We used atom transfer radical polymerization to synthesize poly(butyl acrylate) (PBA) and then substituted the bromo end group with N- ethanol methyl amine to obtain the hydroxyl (OH) end-capped poly(butyl acrylate). A compound of PBA with Mn of about 500 was first synthesized and used as a model compound to investigate the substitution reaction conditions of bromo end group with N- ethanol methyl amine. The OH functionality over 0.8 was obtained when the model compound was reacted with N -ethanol methyl amine under the reaction temperature of 90°C for about 24 h. A poly(butyl acrylate) diol of Mn 2000 with OH functionality of about 1.76 was obtained and characterized by infrared spectrum (IR), hydrogen nuclear magnetic resonance (HNMR) spectra, gel permeation chromatography (GPC) and thermo gravimetric analysis (TGA).
