Abstract

A 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 ^1^H NMR, ^13^C 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).

## Abstract Free radical polymerization of both α‐(trifluoromethyl)acrylic acid (TFMAA) and its methyl ester MTFMA is shown to be possible in the presence of bis(4‐__tert__‐butylcyclohexyl) peroxycarbonate (Percadox) as initiator and dioxane or THF as solvent. Also it is shown that copolymers of TF
