Balance Melting Point and Compatibility of Polypropylene/Syndiotactic1,2-polybutadiene blends By Using DSC
The balance melting point and compatibility of Polypropylene/Syndiotactic1,2 polybutadiene (PP/s-PB) blends and neat PP were studied by using DSC,the results showed that the presence of s-PB in PP would have a strong impact on balance melting point of PP.The presence of s-PB in PP could effectively decrease balance melting point of PP.Balanced melting point depression proves that there are strong interactions between two macromolecular chains in compatible part of blend.According to Nishi-Wang theory,PP and s-PB are incompatible in thermodynamics,but compatible in dynamics.Namely,PP/s-PB are partial compatible.The structure is heterogeneous in microscopy,but homogeneous in macroscopic,this also proves that there are strong interactions between two macromolecular chains in blend.The strong interactions is a kind of useful toughness effect on PP.
