Effect of correlations in the interaction along polymer chain on the globule structure

Abstract

A special potential for interaction between polymer chain units, whose energy decreases with increasing distance s between the units as s^–1, was introduced for the first time. According to Monte Carlo simulation, interactions of this type result in the formation of a globule with an equilibrium packing of domains in space. The radius of gyration of a chain segment in these globules varies with segment length according to the scaling law typical of crumpled globules.
