Molecular weight, Mn (a–e) and Mw (f–j) of OGLs as a function of H2O2 treatment time. (a,f) OGL200L series, (b,g) OGL200M series, (c,h) OGL200S series, (d,i) OGL400L series, and (e,j) OGL600L series were obtained through the room-temperature H2O2 treatment of GLs with H2O2/GL 1:1 and 1:3 mass ratios.
