Table 1.

Peak area and area ratio of the double carbon bonds to the nitrile groups in CTBN/epoxy blends.

Sample	Area-C a	Area-N a	Area Ratio
10-CTBN/E51	9.08	0.19	47.79
10-CTBN(1.5)/E51	8.39	0.31	27.07

^a Area-_C and Area-_N mean the peak area of the double carbon bonds and the nitrile groups in the FTIR spectra, respectively.
