The equilibrium properties of a finite-length linear polymer chain confined in an infinite wedge composed of two perfectly reflecting hard walls meeting at variable apex angle (α) are presented.One end of the polymer is anchored a distancey from the apex on the conical axis of symmetry,while the other end is free. We report here, for the first time the non-monotonic behaviour ofθ-temperature as a function of y for a finite-length chain. Data-collapse for different chain lengths indicates that such behaviour will exist for all finite lengths. We delineate the origin of such non-monotonic behaviour, which may have potential applications in understanding the cellular process occurring in nano-confined geometries.
