The structure of the polymer was characterized by IR, 1H NMR, UV-vis and GPC. The IR and UV-vis spectra demonstrated that azo group was grafted to the polymer in content of 15.56%. The molecular weight of the polymer as determined by GPC was higher than that of the polymer obtained by common method.展开更多
