| Abstract: |
| The development process and reinforcing mechanism of the nano-dispersion phase structure in the in-situ polymerized nano-PZDMA/POE were investig ated by micro-scopy and thermogravimetric analysis and the dependence of the stress-strain behavior and tensile streng th of PZDMA/POE composite on the temperature was also studied.The results showed that the nano-dispersion phase（PZDMA）was formed by the in-situ polymerization of ZDMA during vulcanization；the higher streng th of PZDMA/POE composite was mainly contributed by the physical adsorption relaxation between nano-PZDMA dispersion phase and POE molecule rather than their chemical adsorption relaxation；and the stress-strain curve of PZDMA/POE composite was quite different from that of carbon black/POE compound，i.e.the PZDMA/POE composite gave the much higher tensile strength at the room temperature in contrast to the lower tensile streng th at the elevated temperature when compared to carbon black/POE compound. |
