that the chains become effectively inseparable, further aggregation, by which new chains create stacked structures in which parts of a central chain are sandwiched between two other chains, may result in trapping of the non-equilibrium structure, making these partially overlapping structures even more long-lived. We have quantified this behaviour via N trap , the number of monomers that have a monomer on each face (Fig. ). This variable increased over time in the poor and intermediate solvents, but did not go above zero in the "good" solvent over the simulation duration (Fig. ), highlighting again that the chains in the "good" solvent should be able to rearrange towards the fully overlapping structure, whereas those in the poorer solvents will eventually become trapped in partially overlapping structures.
