摘要
ＰＥＯ以分散相形式存在于ＰＥＯ／ＥＶＡ共混物中，且具有部分相容性。Ｘ－射线衍射谱表明ＥＶＡ含有较强的ＰＥ衍射峰；ＰＥＯ／ＥＶＡ共混物既表现出ＰＥ的衍射峰也含有ＰＥＯ的晶面反射。随着ＰＥＯ的Ｍｎ的增加，ＰＥＯ／ＥＶＡ的Ｗｃ、ｘ增大且于时获得最大值：ＰＥ０／ＥＶＡ的Ｗｃ、ｘ值比纯ＰＥＯ的Ｗｃ、ｘ明显降低。
PEO formod dispersed phase exists into PEO / EVA blends. The blends are partial miscibility, X-ray diffraction results showed that EVA copolymers. possess stronger PE difffection peaks, and PEO / EVA blends have not only PE crystalline peaks, but have also PEO reflection. Degrees of crystallinity (W,x) of PEO/ EVA blends increase with increasing M. (PEO) and obtains maximum values at M (PEO) = 9 ×105. Wc,x values are clearly reduction compared with that value pure PEO.
