Diffusion-limited growth of polymer chains

Abstract
A new self-avoiding walk (SAW) which grows without terminating is introduced as a model of the diffusion-limited growth of linear polymers. The model is in a different universality class than the equilibrium SAW and previously considered kinetic SAW’s with ν=0.774±0.006 in two dimensions and ν=0.56±0.02 in three dimensions. The ‘‘indefinitely growing SAW’’ is shown to emerge as a particular limit of our model.
