Abstract
AbstractA novel synthesis of linear acrylic acid containing polymers, poly(styrene‐co‐acrylic acid) and poly(acrylic acid), was accomplished through hydrolysis of the respective parent polymers, i.e. poly(styrene‐co‐methyl acrylate) and poly(methyl acrylate), with trimethylsilyl iodide under mild conditions. Combination of 1H NMR, 13C NMR, FTIR, DSC and chemical titration confirms that the conversion from methoxycarbonyl to carboxyl is almost complete. This method is further successfully applied to synthesize poly‐(ethyl methacrylate‐co‐acrylic acid) through selective hydrolysis of the methyl acrylate units in poly(ethyl methacrylate‐co‐methyl acrylate).
