| Abstract: |
| The influence of the kind and level of compatibilizer and the blending technology on the physical properties of EPDM/PA blend was investigated.The results showed that CPE was a suitable and cheap compatibilizer for EPDM/PA blend; and its optimal content is 50% by weight of PA.It was found on SEM that the compatibility between EPDM and PA was poor; and the uniform dispersion and small particles were obtained in the dispersive PA/CPE phase by adding CPE into EPDM/PA blend. It was suitable to blend at (160±5)℃, 15 min for PA/CPE and 8 min for EPDM with PA/CPE respectively.The influence of the loading order on the properties of blend was also studied. |
