Abstract

We consider dilute non-adsorbed polymers grafted at an impenetrable surface and compute several quantities which characterize the polymer shape: the asphericity and the ratios of the eigenvalues of the radius-of-gyration tensor. The results are only slightly different from those obtained for polymers in the bulk, showing that the surface has little influence on the polymer shape.
