Quantitative theory and interpretation of the experimental data on the coil-globule transition in the persistent macromolecule

The theory of the globular state and the coil-globule transition has beenconstructed for a persistent macromolecular. The reasons for the universality of the picture of this transition have been explored (its independence from the microscopic characteristics of the polymer). A method of seeking the parameters of the bead model equivalent to a given persistent chain is indicated. A way of evaluating the axial ratio of the macromolecule (ratio of the persistent length l to the thickness d from the experimental data on the coil-globule transition has been found. In cyclohexane and dioctylphthalate l/d approximately equals 2 has been found for PS. The orientation ordering of portions of the chain in the surface layer of the globule is analyzed numerically.
