Poly(epichlorohydrin-g-styrene) graft copolymers were synthesized via “click” reaction (1,3-cycloaddition reaction) between alkyne moiety of well-defined polystyrene and azide moiety of azidated polyepichlorohydrin. Aklyne-terminated polystyrene with predetermined molecular weight and narrow distributions was synthesized through the atom transfer radical polymerization of styrene. And, azidatedpolyepichlorohydrin was obtained by treatment of the polyepichlorohydrin(PECH) with sodium azide in DMF solution, which induces the substitution of chlorine in the PECH by azide anion.The graft copolymers were characterized by1H NMR, FT-IR spectroscopy,GPC,DSC,DMA and UTM. |
