- Abstract:
-
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.
