Using molecular dynamics simulations, we study the dynamics of the spreading of liquid drops of chain molecules on a solid substrate. In contrast to previous work with monatomic or diatomic fluids, the radius of the spreading layers increases with time with a power law compatible with the $\sqrt{t}$ behavior observed experimentally in polymeric fluids.
