Research on the Synergistic Toughening of Homopolymer PP by LLDPE and POE
Polypropylene(PP)is one of the five general plastics,and homopolymer PP features high crystallinity and poor toughness.The compatibility of LLDPE/homopolymer PP is improved by adding POE in order to further improve the low temperature impact strength and comprehensive mechanical properties of cocomposites.The experimental results show that the addition of LLDPE and POE in a certain proportion can reduce the MFR,hardness,flexural elastic modulus and tensile strength of the composites,and the effect of adding POE alone is more obvious.When the total addition amount is less than 15%,adding different proportions of LLDPE and POE can improve the interface combination of LLDPE and PP in ordet to significantly improve the impact performance of PP and display a good toughening effect.
