  We have studied the competition between helix formation and aggregation for a
simple polymer model. We present simulation results for a system of two such
polymers, examining the potential of mean force, the balance between inter and
intramolecular interactions, and the promotion or disruption of secondary
structure brought on by the proximity of the two molecules. In particular, we
demonstrate that proximity between two such molecules can stabilize secondary
structure. However, for this model, observed secondary structure is not stable
enough to prevent collapse of the system into an unstructured globule.
