The equilibrium thermodynamic properties of a linear polymer chain confined to a space between two impenetrable walls (lines) at a distance under various solvent conditions have been studied using series analysis and exact enumeration technique. We have calculated the end-to-end distance of polymer chain, which shows a nonmonotonic behavior with inter wall separation The density distribution profile shows a maxima at a particular value of Around this our results show that the collapse transition occurs at higher temperature as compared to its bulk value of 2d and 3d. The variation of θ-temperature with shows a reentrance behavior. We also calculate the force of compression exerted by the walls (lines) on the polymer.
