    The Studies of Poly (ethylene oxide) with Aliphatic Polycarbonate Blends

    • 摘要: 本文用差热分析(DSC)和红外光谱仪(FTIR)研究了聚环氧乙烷(PEO)和新型聚合物——脂肪族聚碳酸脂(PPC)共混热行为和大分子间的相互作用。由熔点下降方法给出PEO/PPC混合体系在320K下相互作用参数为-0.46;FTIR谱表明PPC大分子链和PEO大分子链存在较强的相互作用;PEO/PPC共混形态随PPC含量增加发生了较大变化。

       

      Abstract: In this paper, the miscibility of aliphatic polycarbonate (PPC) and poly (ethylene oxide) (PEO) blends was investigated by using DSC and FTIR techniques, The depression of melting point of crystalline component in the blends was used to indicate the parti
