A scaling relation for the disjoining pressure of strongly confined polymer\nfluids is proposed for the first time, which yields directly the scaling\nexponent, nu, of the radius of gyration for polymers. To test the proposed\nscaling relation we performed extensive particle based, coarse grained computer\nsimulations of polymers confined under theta solvent conditions and found that\nthe value of nu agrees with the expected value for strictly two dimensional\nchains, nu = 4/7, which points towards the essential correctness of our scaling\nrelation. New approaches are suggested for experimental tests of this scaling\nlaw. This work opens up the way to look for other scaling exponents that may\nreveal new physical regimes and it constitutes an efficient route to determine\nnu because the scaling exponent can be obtained with chains of a single\npolymerization degree by simply reducing the distance between the confining\nplates.\n
