| Abstract | Abstract Series of graft copolymers with [Poly(epichlorohydrin- co -ethylene oxide)] [Poly(ECH- co -EO)] as backbone and polystyrene (PS), poly(isoprene) (PI) or their block copolymers as side chains were successfully synthesized by combination of ring-opening polymerization (ROP) with living anionic polymerization. The Poly(ECH- co -EO) with high molecular weight ( M n = 3.3 × 10 4 g/mol) and low polydispersity index (PDI = 1.34) was firstly synthesized by ring-ROP using ethylene glycol potassium as initiator and triisobutylaluminium ( i -Bu 3 Al) as activator. Subsequently, by “grafting onto” strategy, the graft copolymers Poly(ECH- co -EO)- g -PI, Poly(ECH- co -EO)- g -PS and Poly(ECH- co -EO)- g -(PI- b -PS) were obtained using the coupling reaction between living PI − Li + , PS − Li + or PS- b -PI − Li + species capped with or without 1,1-diphenylethylene (DPE) agent and chloromethyl groups on poly(ECH- co -EO). By model experiment, the addition of DPE agent was confirmed to have an important effect on the grafting efficiency at room temperature. Finally, the target graft copolymers and intermediates were characterized by SEC, 1 H NMR, MALLS and FTIR in detail, and thermal behaviours of the graft copolymers were also investigated by DSC measurement. |
