The Flory-Huggins model without solvent molecules on a brick lattice is solved exactly by the Bethe ansatz. It is shown that polymer melting given by this model is a second order transition which verifies the conjecture of Gujrati and Goldstein. It is also found that the gauche fraction turns out to be zero in the low-temperature phase.
