Abstract

The influence of petroleum resin on the thermal oxidation of an ethylene copolymer with vinyl acetate was studied with differential scanning calorimetry, FTIR infrared spectroscopy, and physicomechanical tests. We found that the introduction of PPR into EVAC inhibits the accumulation of oxygen-containing groups in the polymer. The use of the resin combined with an Irganox 1010 primary antioxidant makes it possible to maintain the performance of a material after holding at higher temperature for 3 h at a significantly higher level than in the case of only Irganox 1010.

石油聚合物树脂存在下乙烯共聚物与乙酸乙烯酯的热氧化

摘要

采用差示扫描量热法、FTIR红外光谱和物理力学测试研究了石油树脂对乙烯-醋酸乙烯共聚物热氧化的影响。我们发现将PPR引入EVAC中可以抑制聚合物中含氧基团的积累。将树脂与 Irganox 1010 主抗氧化剂结合使用，可以使材料在较高温度下保持 3 小时后的性能保持在明显高于仅使用 Irganox 1010 的情况。
