Abstract
We describe scaling arguments and simulations of the kinetics of irreversible polymer collapse. Scaling predicts and simulations confirm that irreversible collapse is dominated by diffusion of the polymer ends which accrete monomers and small aggregates. Exponents found by simulations agree closely with scaling relations. In three dimensions the collapse time is predicted to scale only linearly with polymer length. Our results are contrasted with deGennes' mean field theory of collapse in the reversible regime of small departures from θ-solvent conditions.Keywords
