โœฆ Synopsis


Data on mechanical properties of blends of low density polyethylene with nylon-6 as a function of the composition are presented, They suggest that these blends are immiscible in the solid state. However both a theoretical model and scanning electron microscopy seem to indicate some degree of interaction at high content of nylon.

Rheological properties of low density polyethylene/nylon-6 blends have been studied both in shear and in non-isothermal extensional flow. The results show that the rheological properties do not vary linearly with the composition. They indicate complete immiscibility in molten state and show that th

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

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 rheologi
