Torque values and mechanical properties are reported for blends of low density with linear low density polyethylene (PE). The torque values show that incompatible mixtures in the molten state are formed when the torques of the pure polymers are almost equal. Semicompatible behaviour is shown in the

β¦ Synopsis
Rheological and mechanical data on LLDPE/LDPE blends are presented in order to evaluate the influence of the structure of LLDPE on the properties of these blends. The influence of the comonomer type is negligible, while the molecular weight exerts an important effect on properties. For both rheological and mechanical properties, the blends made from LLDPE of large MFi seem the more interesting.

## Abstract The effect of the branch content (BC) and composition distribution (CD) of linear lowβdensity polyethylene (LLDPE) on the thermal and mechanical properties of its blends with LDPE were studied. All blends and pure resins were conditioned in a Haake PolyDrive blender at 190Β°C and in the
