An iron-porphyrin mesohemin based catalyst, derived from the active center of proteins such as horseradish peroxidase, hemoglobin, etc., was evaluate for the direct atom transfer radical polymerizations (ATRP) of methacrylic acid. With <b>m</b>esohemin based catalysts, controlled radical polymerization of methacrylic acid was successful, providing poly(methacrylic acid) with M<sub>n </sub>= 20,000 and with low dispersity (MWD&lt;1.5) Successful synthesis and modification of mesohemin derivatives for this application was achieved.
