选择两组分玻璃化温度较远的PEO/PMMA以及玻璃化温度相近的SAN/PMMA两个均相共混体系为研究对象,考察了组分组成对共混物α内耗峰峰高、峰宽以及温频关系的影响.结果表明,共混物α内耗峰峰高及温频关系介于纯组分之间,随组分组成有规律地变化;PEO/PMMA体系的弛豫谱明显地比纯组分的宽,而SAN/PMMA体系的弛豫谱宽度跟纯组分的相差不多.认为由于PEO/PMMA两组分的玻璃化温度相差甚远,组成涨落造成玻璃化温度及弛豫时间的分布变宽,因而弛豫谱也很宽.

The effects of component composition on the relationship between peak height, peak width and temperature frequency of the blends α internal consumption of the blends were investigated. The results showed that the relationship between peak height and temperature frequency of the α internal consumption of the blend was between the pure components, and changed regularly with the composition of the components. The relaxation spectrum of the PEO/PMMA system is significantly wider than that of the pure component, while the relaxation spectrum width of the SAN/PMMA system is similar to that of the pure component. It is believed that because the glass transition temperature of the two components of PEO/PMMA is very different, the distribution of glass transition temperature and relaxation time becomes wider due to the fluctuation of composition, so the relaxation spectrum is also wide.
