摘要
用热重 -红外光谱联用分析技术 ,研究了高温条件下聚酯 (PET)的热稳定性和热氧稳定性 ,表明由于氧的存在 ,PET的起始失重温度大大地降低 ,以至低于 PET树脂的最低熔融加工温度 。
The high temperature stability of polyester (PET), thermal stability and thermal oxidative stability,was studied by thermal gravity infrared spectroscopy.It is shown that the starting temperature of weight loss reduces greatly due to existence of oxygen,so much as lower than the minimum temperature of melt formation of polyeste resin,and that the thermal oxidative stability of polyester is an important factor with relation to formation and product properties of polyester.
