Abstract

The difference between the dispersion of the components in two mechanically blended films of polyethylene and polypropylene was investigated by means of optical microscopic and mechanical tests. The films were cast from melts at 230°and 270°C. The results show that a film cast at 270°C has better continuity than a film cast at 230°C, both having the same composition.
Furthermore, the results obtained by the simultaneous measurement of creep and birefringence show that the PE phase in the film of the blends deforms easier than the PP phase.
