| 摘 要： | 根据对聚酰胺类高聚物红外光谱的类比和对聚酰胺6试样进行氘化和碘处理后红外光谱的改变,以及根据对拉伸过的聚酰胺6薄膜试样的偏振红外光谱的观察,我们对聚酰胺6红外光谱中400cm-1—1400cm-1之间的主要吸收带,作了如下解释:1370cm-1吸收带为ν(cщN);1265cm-1和1205cm-1吸收带为δN-H+ν(cщN)(酰胺Ⅲ);1170cm-1吸收带为ν(cN);730cm-1吸收带为γ(CH2)当(CH2)n的n≥4时];690cm-1吸收带为δN-H(面外);580cm-1吸收带亦为δN-H(面外)。

| Abstract: | Based on the comparison of the infrared spectra of polyamide homologues, on the changes in the infrared spectra of deuterated and iodine-treated samples of polycaprolactam, and also on the observations of the infrared dichroism of drawn film, the main absorption bands of polycaprolactam in the region 400 cm-1-1400cm-1, which are rather structure sensitive, have been assigned as follows: 1370 cm-1 band-νC-N; 1265 cm-1 and 1205 cm-1 bands-δN-H+ν(C-N)(Amide Ⅲ); 1170 cm-1 band-νC-N; 730 cm-1 band-γCH2 of (CH2)n when n≥4; 690 cm-1 band-δN-H (out of plane, Amide V); 580 cm-1 band -δN-H (out of plane). |
