Abstract : The viscosity of a polymer melt is calculated by assuming that the relaxation process results from the reptation of an elastic polymer in a thin tube. The mathematical model used here is similar to a model proposed by Doi, and is treated in great detail. Unfortunately, it appears that the experimental results cannot be reproduced in this way and that a more realistic approach is needed.
