## Abstract Relationships between the rheological properties and the molecular weight distribution of two polypropylene series with different molecular weight distribution characteristics were studied. The end correction coefficient in capillary flow is determined by the molecular weight __M__~__w_
The rheological properties of a polymer melt (polydimethylsiloxane) have been measured for fractions and unfractionated polymer in steady shear flow and in relaxation and recovery after steady shear flow. The limiting values of the viscosity and normal stress coefficient at low shear rates have been
