摘要
用X-射线衍射和DSC,研究了用成核剂制得主含β-晶的的聚丙烯试样,在油浴及DSC样品池内等温结晶及不同条件热处理的各种样品的结晶度、β-晶相对含量及热熔行为;讨论了它们的变化情况及原因,阅明了伴随有重结晶现象的热熔过程的热历史影响。
Samples of Ipp with major β-form crystals obtained by using nucleating agents, crystallized isothermally either in oil bath or in sample cells of DSC, of them some were further thermally treated under different conditions. Their crystallinity, relative contents of β-form crystals, and DSC melting behaviors were studied. It was found that the melting process and the occurrence of recrystallization during melting depend on the thermal history of the samples.
