Physical Review Letters 66, 719–722. The abstract identifies end-grafted polydimethylsiloxane on porous <silicon dioxide> and reports thickness proportional to $M\sigma$ in a <poor solvent> and $M\sigma^{1/3}$ in a <good solvent>. The chemical system in that abstract differs from the <polystyrene> wording of the 2016 exam; the scaling comparison is unaffected.
