Small-angle neutron scattering is used to study the conformation of polymer chains of various lengths, N ∼ 1200−7000, in good solvent confined to the energetically neutral pores of a model Vycor glass with a mean pore diameter of D = 70 Å. This study utilized an external polymer concentration, c fre...
