Interestingly, varying the number of DCPAM chains N DCPAM from 5 to 15 has little impact on chain conformations, as indicated by the nearly constant ⟨R 2 ee ⟩/⟨R 2 g ⟩ values. This invariance implies that chain conformations are primarily dictated by intra-chain interactions rather than inter-chain effects or crowding within the studied concentration range. These findings highlight that the chain architecture, particularly the block ratio m : n, exerts the most significant influence on chain conformation, outweighing external factors such as salt and polymer concentrations.
