Abstract
The rheology of polyethylene blends is discussed with an emphasis on those containing the linear low density polyethylenes, LLDPE. Flow of LLDPE with other types of LLDPE's, with low density polyethylene, LDPE, and with polypropylene, PP, was studied in steady state shear, dynamic shear and uniaxial extensional fields. Interrelations between diverse rheological functions are discussed in terms of the linear viscoelastic behavior and its modification by phase separation into complex morphology. One of the more important observations is the difference in elongational flow behavior of LLDPE/PP blends from that of the other blends; the strain hardening (important for e.g. film blowing and wire coating) occurs in the latter ones but not in the former.
