We study a shape change of spherical micro-emulsion droplets when water-soluble polymers are confined inside of them. Upon confinement, spherical droplets deform to prolate ellipsoid droplets while keeping the total surface area and the total enclosed volume of all the droplets constant. We found that an increase of the degree of polymer confinement causes an increase in the uniaxial anisotropy of the prolate droplet, which leads to an isotropic-nematic transition in the concentrated droplet region. As a possible origin of this structural transition, we consider a loss of the conformational entropy of polymer chains due to the confinement.
