Determination of Methyl (Comonomer) Content in Polyethylene by Fourier Transform Infrared Spectrophotometry (FT-IR)
用FT-IR红外光谱法快速测定聚乙烯共聚物中的甲基含量

The effect of different comonomer on the infrared spectrum of polyethylene in polyethylene copolymer is studied. An analysis method for fast determining the methyl (comonomer) content in polyethylene copolymer by infrared spectrophotometry is established. The analysis method has been effectively used in monitoring the methyl content in polyethlene.
