A method for the synthesis of diblock copolymers, by preparing ω-aldehyde-functionalized polymers anionically and employing these as macromolecular terminators for ring-opening metathesis polymerization (ROMP) was discussed. The Quirk and Kuang's method was used to prepare near-monodisperse polystyrene and polyisopropene bearing a single aldehyde functionality at the chain end. Several milliliters of degassed methanol was added with the vigorous stirring to liberate the polymeric aldehyde. The shift of the major peak to shorter elution time relative to the first block indicated successful block copolymer formation.
