摘要(Abstract)：

考察了氧化聚丙烯(OPP)的存储条件,研究了共单体苯乙烯(St)、二乙烯苯(DVB)和季戊四醇三丙烯酸酯(PETA)对马来酸酐(MAH)固相接枝OPP的影响,并利用傅里叶变换红外光谱(FT-IR)对接枝物结构加以表征。实验结果表明,随存放时间增加氢过氧化物含量呈现先快后慢的下降趋势,保护气氛和温度对OPP储存均能产生一定的影响;St、DVB和PETA对MAH接枝OPP均具有明显的改善作用,MAH的接枝效率分别达到74.80%、94.31%、76.33%,并且加入St、PETA的接枝物凝胶率远远低于加入DVB的接枝物。FT-IR分析表明,MAH和共单体与OPP发生了接枝共聚反应,多官能团共单体PETA的C=C双键部分参与了接枝反应,DVB的乙烯基则反应比较完全。
