The styrene-butadiene (SB) micellar lattices prepared by quiescently cooling the disordered solution at high temperatures were examined to study the polycrystalline structure and equilibrium elasticity of the diblock copolymer. The difference between equilibrium modulus and the expected equilibrium modulus for corona blocks was examined using shear-orientation techniques. The results showed that the defects were not responsible for the difference in equilibrium modulus instead osmotic constraint correlation reduced the effective number density of the entropic strands to give larger difference between expected and observed equilibrium modulus.
