摘要
Abstract
Dynamic mechanical measurements have been done during cooling process in PMMA. Results show that at a slow cooling condition, cooling rate doesn't affect the value of α internal friction peak temperature (Tα). It suggests that even if Tα is not very different from Tg at low frequency, both temperatures differ in their nature: Tα is nearly not dependent on cooling rate (at least at a slow cooling process), while Tg is dependent on cooling rate strongly. At a rapid cooling condition, the dynamic mechanical behavior of PMMA has also been investigated tentatively.关键词
