摘要

研究了在室温下，真空或空气条件下γ射线对添加对-叔丁基杯[4

]

芳烃（CA [4

]

）的聚丙烯的辐射效应，同时与加有2

6-二叔丁基对甲酚（BHT）和未加添加剂的聚丙烯对照。由辐照前后聚合物的力学性能、热性质及红外光谱的变化表明，在辐照过程中和辐照后，CA [4

]

对聚丙烯都具有稳定化作用，剂量较高时，稳定化效果更为显著。此外，ESR实验证实，CA [4

]

分子在辐照下产生稳定自由基。在剂量率6.5×10

Gy/h，剂量≤1000kGy，未检测到CA [4

]

的分解碎片，表明杯环具有较高的抗辐射稳定性。

Abstract

Polypropylene (PP) containing cyclic phenolic antioxidant

p-tert-butylcalix [4

]

arene as additive was irradiated with γ-ray in air or in vacuum at ambient temperature. The mechani

cal properties

variation of IR spectra and decomposition temperature by thermal analysis were mearsured for the irradiated PP sheets. Compared with BHT

p-tert-butylcalix [4

]

arene showed radiation stabilization towards PP during and after irradiation

especially at a high dose. By means of ESR spectra and other spectra the formation of the stable calix [4

]

arene radical was confirmed. No decomposition species of the calixarene was observed with the dose≤1000 kGy and the dose rate of 6.5×10

kGy/h indicating the higher radiatior-resistance of the calix arene structure.
