用差示扫描量热仪观察了聚对苯二甲酸乙二酯(PET)/离子聚合物surlyn体系的结晶行为.用扫描电镜和偏光显微镜观察了PET/surlyn体系的形态.surlyn有显著的成核效果.surlyn的碳氢主链为柔性分子链.它会促进PET的分子运动,从而提高PET在低温区的结晶速度.但它对PET的球晶形态却没有影响,PET仍为正常球晶.surlyn在PET中是分相的,随着surlyn与PET之间反应程度的加深,surlyn的宏观分相就消失了.
The crystallization behavior of PET / Surlyn system was observed by differential scanning calorimeter. The morphologies of PET / Surlyn system were observed by scanning electron microscopy and polarized light microscopy. Nuclear effect.Surlyn’s main chain of hydrocarbon molecules for the flexible molecular chain.It will promote the molecular movement of PET, thereby enhancing the crystallization rate of PET in the low temperature region.But it has no effect on the spherical morphology of PET, PET is still normal spherulites Surlyn is phase-separated in PET and surlyn’s macroscopic phase disappears as surlyn’s response to PET deepens.
