Popis:	NMR results with polystyrene glass obtained by freeze-drying dilute solution show unambiguously that substantial interpenetration exists among polymer chains in a material obtained by quenching a solution for which c * /c ∼ 4 in liquid nitrogen and freeze-drying it (c * is the critical overlap concentration at room temperature)
