用ＦＴＩＲ光谱证实了ＰＶＣ与ＰＥ８ＤＢＭ（简称ＦＰＥ）之间存在着氢键和偶极偶极的作用，其中以氢键作用为主。测定了ＰＶＣ／ＣＰＥ／ＰＥ和ＰＶＣ／ＣＰＥ／ＦＰＥ合金的力学性能，用ＤＳＣ、相衬显微镜及ＳＥＭ表征了这两个体系的微观形态结构，研究了共混物中异种分子间的相互作用对合金性能与形态结构的影响
FT-IR spectroscopy confirmed the existence of hydrogen bonding and dipole-dipole interaction between PVC and PE-8-DBM (FPE), of which hydrogen bonding was the main factor. The mechanical properties of PVC / CPE / PE and PVC / CPE / FPE alloy were measured. The microstructure of these two systems was characterized by DSC, phase contrast microscope and SEM. The interaction between different molecules in the blend Effect of Alloy Properties and Morphology Structure
