Poli(β-Propiyolakton)-b-Poli(Metil Metakrilat) Üç Kollu Blok Kopolimerinin Atom Transfer Radikal Polimerizasyonuyla Sentezi ve Karakterizasyonu

Terminally dibrominated poly(β-propiolactone) was prepared through sequentially ring-opening polymerization of β-propiolactone and dibromination the former product. Synthesis poly(β-propiolactone)-b poly(methyl methacrylate) tri-arm block copolymer achieved by atom transfer radical methyl methacrylate onto with bromide end groups. The characterization polymers carried out using 1H-NMR, DSC, TGA, GPC. GPC analysis final product resulted in an unimodal curve corresponding to weight average molecular 9353 g.mol-1. TGA exhibited a two-step decomposition blocks at 212 oC 411 oC, respectively. DSC showed two glass temperatures -22.02 86.55 spectroscopic thermal analyses proved that successfully synthesized polymerization,
