EQUILIBRIUM PROPERTIES OF A POLYMER-CHAIN IN AN EULER FLUID

A field theoretical formulation for the motion of a polymer chain in an Euler Fluid was analyzed. Using a projection formalism an exact representation of the effective chain action was obtained. The mean field approximation gives an effective equation of motion for the polymer chain in the Euler fluid. As a result of the interaction between chain and liquid, we get a general effective friction, stochastic forces, and an additional attractive contribution to the potential for the polymer chain. The influence of this contribution to the equilibrium end to end distance and diffusion properties of the polymer chain are discussed.
