A new method to detect the glass transition was used to investigate the effects of physical aging on the glass transition of polystyrene by Fourier transform infrared (FTIR) spectroscopy. The results showed that the onset point of the glass transition shifted to higher temperature with aging, but...
(10.41±1.13)×10—5 mol/g,此时温度的升高导致羰基稳定性变差,导致其分解速率增大,因此,在250~265℃羰基的增长速率减缓;当温度为265℃时聚丙烯在热氧降解过程中产生的羰基含量最高,为(11.82±1.52)×10—5 mol/g;当样品温度超过265℃,羰基的分解速率大于其生成速率,使得羰基含量呈下降趋势.%The polystyrene(...
This is the most well-known spectrum in IR spectroscopy: polystyrene. A polymer with CH2 and benzene groups. For interpretation purposes, we can describe what are called functional groups which always occur at similar positions in the spectrum: OH vibrations, CH2 vibrations, Aromatic vibrations. ...
FTIR的有效性验证 这次谈谈FTIR 的有效性验证。英语中的Validate 一词有『（在法律上）使之生效』的意思。在百货商店等购物后，收银台小姐在停车卷上加盖『免费』章（在美国加盖Valid)，这在英语中也称为Validate 。通过对装置进行必要的检查，确认该装置已可正常运转，使装置“生效”，是“可以使用”的。从这个...

Mutual diffusion at PS/PVME (polystyrene/polyvinyl methyl ether) interface both below and above the glass transition temperature, Tg, of polystyrene was probed by Attenuated total reflection (ATR) and rheometry techniques. The results were analyzed with a simple three layer model and a combination...
