摘要

Star polymer undergoes a transformation from a group of loosely coupled chains at low number of arms to a dense hairy colloid at their high number. This change affects solubility, aggregation, and rheological behavior and is of much practical interest. The range of size and shape properties of the star molecule and of its individual arms upon this transformation are studied. Theoretical calculations are based on a continuous chain model and are performed in the first order in epsilon = 4 -d. Computer simulations are done by the dissipative particle dynamics and in part by Monte Carlo method and the results demonstrate very good agreement with the selected set of properties known from the previous simulations. Theory and simulations provide qualitatively similar trends upon increase of the number of arms, but higher order of approximation is required in a theory to achieve a good quantitative agreement.
