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_(c_щN);1265cm~(-1)和1205cm~(-1)吸收带为δ_(N-H)+ν_(c_щN)(酰胺Ⅲ);1170cm~(-1)吸收带为ν_(c_N);730cm~(-1)吸收带为γ_(CH_2)[当(CH_2)_n的n≥4时];690cm~(-1)吸收带为δ_(N-H)(面外);580cm~(-1)吸收带亦为δ_(N-H)(面外)。
Based on the analogy to the infrared spectra of the polyamide-based polymers and the changes of the infrared spectra after deuteration and iodine treatment on the samples of polyamide 6, and the observation of the polarization infrared spectra of the drawn polyamide 6 film samples , We have explained the main absorption bands between 400cm -1 and 1400cm -1 in the infrared spectrum of polyamide 6. The 1370cm -1 absorption band is ν_ (c_щΝN) (-1) and 1205cm -1 were δ_ (NH) + ν_ (c_щ) (amide Ⅲ); ν_ (c_N); 730cm -1 absorption band Is δ_ (NH) (out-of-plane). The absorption band of 580cm ~ (-1) is also δ_ (NH) (Out of plane).
