文摘

We report for the first time by computer simulations, evidence of polymer chain collapse near a lower critical solution temperature (LCST). Continuous space, Monte Carlo simulations have been performed on freely jointed, Lennard-Jones chains in a LJ monomeric solvent with symmetric energetics. The LCST phase boundary and associated chain collapse in the supercritical solvent region has been established for chains of size 20. This Letter focuses on why the chain collapses near a LCST.
