Abstract
Regular star polymers with functionality f = 64 and f = 128 have such high segment density that they resemble ''hard sphere'' objects in dil ute solution. In semi-dilute solution they form a macrocrystalline ord ered phase with spacings of the order of 100 to 500 Angstrom. They are physical gels. Their melt properties are characterized by a long term relaxation process not found in stars with fewer arms.
