| Abstract: |
| The influence of blending ratio of polypropylene with polyamide，EPR or NR on the mechenical properties of their binary or ternary blend was investigated.The toughening mechanism of polypropylene was analysed.For the toughened polypropylene，the tensile strength was not less than 24 MPa，the simple beam impact strength not less than 9 kJ·m-2，bending modulus not less than 550 MPa，the brittle temperature was lower than that of basic polypropylene by more than 10 ℃.
An experimential formula was given to evaluate the influence of levels of main components on the mechenical properties of the blend. |
