摘　　要：采用傅立叶变换红外光谱法对PP和PE的共混物进行了分析。结果表明 :用红外光谱法可以测定PP/PE共混物中PE的含量和结晶度 ;PP与质量分数为 0～ 10 %的PE熔融共混后 ,其红外光谱未见明显偏离两者各自的特征 ,但是差谱结果表明PE与PP存在一定的相互作用。PP/PE blend was analyzed by Fourier transform infrared spectroscopy. The results showed that the content and the crystallinity of PE in PP/PE blend can be measured by infrared spectrum analysis. No obvious difference was observed in their characteristics after PP was blended with PE of 0-10% by weight mass. But the difference spectrum showed that mutual effect existed between them.
