Conclusion
Modification natural rubber with dibutyl phosphate were successfully performed, as proved by FTIR absorption
peaks at1030, 1069 and 1279 cm
-1
. It was also found that the highest degradation temperature(T
d
) was 393
o
C. In
addition, it was found that the dynamically cured 60/40 DSNR/PP blends with mixed sulphur-peroxide cured showed the
superior mechanical and dynamic properties and smallest rubber domians dispersed in the PP matrix.
