Phys. Rev. E 80, 041806 (2009) [10 pages]Conformational free energy of melts of ring-linear polymer blendsReceived 23 July 2009; published 21 October 2009 The conformational free energy of ring polymers in a blend of ring and linear polymers is investigated using the bond-fluctuation model. Previously established scaling relationships for the free energy of a ring polymer are shown to be valid only in the mean-field sense, and alternative functional forms are investigated. It is shown that it may be difficult to accurately express the total free energy of a ring polymer by a simple scaling argument, or in closed form. © 2009 The American Physical Society URL:
