用~(13)C和~1HNMR波谱,探讨了聚环氧氯丙烷(PEPCH)的辐射效应,结果表明随着辐射剂量的增加,本体聚合物的~(13)CNMR谱中各基团的分辨率得以提高,~1HNMR谱中出现了裂解产物共振峰,T~1变短,表明PEPCH在限量空气氛中的辐射效应以大分子裂解反应为主,并通过特性粘度的测定,得到了证实。
The radiation effects of polyepichlorohydrin (PEPCH) were investigated by ~ (13) C and ~ 1HNMR spectroscopy. The results showed that the resolution of each group in ~ (13) CNMR spectra of bulk polymers increased with the increase of radiation dose The results show that the cleavage product resonance peak appears in ~ 1HNMR spectrum and T ~ 1 becomes shorter, which indicates that the radiation effect of PEPCH is dominated by macromolecular cleavage reaction and confirmed by intrinsic viscosity measurement.
