| Abstract: | Summary We tried to correlate the rheological properties in dynamic mode with the calendering ability of polypropene. Complex dynamic viscosity experiments have been correlated with the calendering processing using the relaxation times distribution spectra. These spectra allow to classify the materials according to their ability to calendering. Associating the bank to a long times range and the nip to a short times one, it is possible to give a rheological explanation of defects such asV-shaped defects or sharkskin.With 1 figure and 1 table |
