| Abstract: |
| By the initiation of a rubber accelerator，grafting of maleic anhydride（MA）onto EPDM was accomplished to form a copolymer which serves as a compatibiliser for EPDM/polyamide（PA）blends.The MA grafting reactions on EPDM were carried out under various experimental conditions.It is shown that as the amount of EPDM-g-MA increases from 0 to 14 wt% based on total rubber，the tensile strentgth increases from 4MPa to 12MPa and solvent resistance is greatly improved too.SEM photos indicate that the polyamide particles in EPDM/EPDM-g-MA/PA blends are much smaller than that in EPDM/PA blends.Differential scanning calorimetry（DSC）measurement shows that EPDM/EPDM-g-MA/PA blends have two glass transition temperatures,-45.2 ℃ and 48 ℃，corresponding to the Tg of EPDM and PA.Therefore the EPDM/EPDM-g-MA/PA vulcanisates are multiphase systems. |
