Effect of the percolation of NR on mechanical properties of HDPE/PP/NR blends

The effect of the connectivity of an elastomer in a blend of two polyolefins was studied. Blends of natural rubber (NR) with high density polyethylene (HDPE) and polypropylene (PP) were prepared using a Banbury mixer at 180°C. The samples were laminated by compression molding at 180°C and quenched in water at room temperature. Extraction of the natural rubber was performed for blendscontaining equal relative amounts of both polyolefins. The percolation of the rubber within the matrix of both polyolefins started to occur at about 20% rubber content. Mechanical properties, such as Young's modulus and stress at break, showed the effect of the percolation phenomenon.
