摘要
采用红外(IR)光谱进行了聚乙烯的结构研究,结果表明,聚乙烯主要存在νa(s CH2–聚乙烯)、νs(CH2–聚乙烯)、δ(CH2–聚乙烯)和ρ(CH2–聚乙烯)等红外吸收模式。采用变温红外(TD-IR)光谱进一步进行了聚乙烯的热稳定性研究,结果表明,在303~423 K,聚乙烯的热稳定性明显下降。
The structure of polyethylene was investigated by using the infrared(IR)spectrum.The results show that the main infrared absorption modes of polyethylene areνas(CH2-polyethylene),νs(CH2-polyethylene),δ(CH2-polyethylene),ρ(CH2-polyethylene)and so on.The thermal stability of polyethylene was further investigated by using the temperature-dependent infrared(TD-IR)spectrum.The results show that the thermal stability of polyethylene obviously decreases in 303~423 K.
