Abstract
A method for the in-situ preparation of an ionic comonomer, such as zinc dimethacrylate, dissolved in styrene monomer, for use in production of polystyrene is disclosed. The method generally includes adding comonomer chemical precursors to a solution of styrene and nonionic surfactant. The resulting ionic comonomer may be further dissolved in styrene and polymerized to form a product that may have improved properties.
