Rheological behavior of LDPE/CaCO 3 blends containing EAA
Calcium carbonate (CaCO 3 ) filler particles were surface treated with organic titanate (TTS), a coupling agent. The composites were prepared by blending low‐density polyethylene (LDPE) with the surface‐modified fillers at various weight ratios. Ethylene‐acrylic acid copolymer (EAA) was added to imp...

The composites were prepared by blending low‐density polyethylene (LDPE) with the surface‐modified fillers at various weight ratios. Ethylene‐acrylic acid copolymer (EAA) was added to improve the adhesion of LDPE to fillers. A capillary rheometer was used to evaluate rheological properties of the LDPE/CaCO
