We re-examine quantitative mean-field theory for the collapsed globule phase of a polymer chain taking full account of its finite compressibility. The mathematical properties of the nonlinear mean-field equations describing the structure of the globule are formulated. Our results explain findings and observations of the recent computer simulation and experimental studies. While the effects are due to the restricted compressibility, they are seen well before the globule reaches its dry maximal density.
