Synthesis and Characterization of Poly(β-Propiolactone) b-Poly(methyl methacrylate) Tri-arm Block Copolymer Using Atom Transfer Radical Polymerization

Öz

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