The polystyrene macromonomer(SSTM) can be obtained from a reaction of a living polystyrene initiated with alkyllithium and terminated with p-chloromethyl styrene (PCMS).

To synthesize well-defined H-shaped (PS)nPI(PS)n nonlinear block copolymers it is a common practice to react comb-shaped (PS)nPI with ifunctional coupling agent 1,2-dibromoethane(DBE).
