According to mastication degradation mechanism and long-chain molecular model
the equation of TQ= TQ0(t+1)-n was introduced to reveal the rheological behavior of HDPE/NR blends.DSC results showed that partial NR chains rheowere clamped by HDPE crystals and thus act as the tie molecules in the blend.Small amount of NR can improve HDPE's tensile elongation and environmental stress cracking resistance dramatically
while the melt flow property maintained because of the degradation of NR.
