Abstract
A composition of matter includes a mixture of styrene derivative monomers and methacrylate/acrylate derivative monomers, which have one or more urethane, carbamate, amide, and/or amine functional groups, and initiators, and the compositions are used to achieve composition control of the forming polymer, with the mole fraction of acrylate/methacrylate and styrene moieties in the forming polymer determined preferably by the chemistry and composition of the feeding monomers rather than the viscosity of the monomers.
