| 摘 要： | 四种抗氧剂(A、M、RDH、264)中,AM是能添加入聚乙炔膜内的一种有效抗氧剂。用氧化增重和红外分析研究了四种聚乙炔膜(PA,PA/SBR,PA/AM,PA/SBR/AM)暴露于空气中的氧化及异构化动力学行为。研究表明,各种膜在室温(25℃)空气中的耐氧化性能和抗异构化能力的次序相同:PA/SBR/AM>PA/AM>PA/SBR>PA。添加抗氧剂AM于聚乙炔中,不影响掺杂聚乙炔的优良电性能及其它性能。

| Abstract: | From a comparison of several antioxidants(AM,RD,Hand 264), AMis a powerful antioxidant which can be added into polyacetylene(PA). The kinetics of oxidation and isomerization of PA, PA/SBR, PA/AM, and PA/SBR/AM films have been established by oxidation-weight gain and infrared spectro-photometric analyses. Oxidation of all films is a first-order process comprised of one or two distinct regions. The induction period of oxidation for PA/SBR/AM film is the longest of all films cis-trans isomerization of PAfilms also shows two or three first-order kinetic regions. The antioxidation and anti-isomerization ability of various PAfilms exposed to air at 25℃ decreased in the following order:PA/SBR/AM>PA/AM>PA /SBR>PA. The addition of AMhas no influence on the conductivity possessed by doping PA. It is of significance for use of PAin industry. |
