Synthesis and characterization of the graft copolymer including polyβ-butyrolactone and polyvinyl chloride by ring-opening polymerization and “click” chemistry

Synthesis of poly(vinyl chloride-g-β-butyrolactone) [poly(VC-g-BL)] graft copolymer was carried out by means “click” chemistry terminally propargyl polyβ-butyrolactone ester (PBL-propargyl) and polyvinyl chloride with pendant azido group (PVC-N3). PVC-N3 synthesized reaction purified PVC sodium azide. PBL-propargyl obtained the β-butyrolactone alcohol ring-opening polymerization. By using PBL-propargyl, poly(VC-g-BL) synthesized. The concentration amount solvent that influenced reactions were evaluated. characterization products accomplished multi-instruments methods such as 1H-NMR, FT-IR, TGA, DSC, static light scattering, elemental analysis.
