摘要
Molded articles formed of polystyrene or other polymers containing an aromatic moiety can be derivatized on the surface of the article by subjecting the molded article to a chemical reaction wherein the reaction media utilizes tetramethylsulfone as the reactant solvent and a suitable substituent group which is substituted on to the aromatic moiety of the polystyrene or other polymer by electrophilic substitution. By choosing the substituent group to further include a leaving group, further substitution of the primary substituent can be effected normally by nucleophilic substitution reaction. In this way, biologically important molecules can be attached to a polystyrene or other aromatic containing polymer without effecting certain properties of the molded article such as its optical or spectroscopic clarity.
