- Abstract
- 3-Amino-1, 2, 4-triazole (ATA) (2.5 and 5.0 phr) was incorporated into a immiscible maleated ethylene propylenediene rubber(mEPDM)/maleated high density polyethylene(mHDPE) (50 wt%/50 wt%) blend by melt mixing. Effects of theATA on structure, mechanical and rheological properties of the blend was investigated. FT-IR and DMA results revealedthat supramolecular hydrogen bonding interactions between the polymer chains occur by reaction of ATA with maleic anhydridegrafted onto the component polymers in the blend, which induces the physical crosslinks in the blend. FE-SEM analysisshowed that mEPDM forms a dispersed phase in continuous mHDPE matrix, and the blend with the ATA has finer phasemorphology as compared to the blend without the ATA. By the addition of ATA in the blend, there were significant increasesin tensile strength, modulus and elongation-at-break as well as elastic recoverability. Melt rheology studies revealed that ATAinduced substantial increase in storage modulus and complex viscosity of the blend at the melt state.
