Abstract
A monomer mixture containing asymmetric and symmetric esters of itaconic acid which can be used as a reactive diluent. In addition, copolymers resulting from the polymerization of such monomer mixture. The monomer mixture more specifically includes the asymmetric monomers methyl ethyl itaconate (MEI) and ethyl methyl itaconate (EMI) and the symmetric monomers dimethyl itaconate (DMI) and diethyl itaconate (DEI).
