The dynamics of a system of long polymer chains is investigated numerically with Monte Carlo dynamics. By use of a lattice model of polymers interacting via hard-core potentials, much longer polymers have been investigated than has been possible previously. The correlation functions calculated are in agreement with de Gennes's "reptation" hypothesis, and differ strongly from Rouse-like behavior.
