“…3(a) shows the DSC results with the heating rate of 2.5 K/min. When x= 0, 25,30,35,40, there was an obvious crystallization peak; when x= 5, 10, 15, there was a weak crystallization phenomenon; when x=20, there was no crystallization. When the heating rate was 5 K/min, as shown in Table 1, no crystallization occurred in the compositions of x=10, 15, and 20.…”
