The structural determination and manipulation of bottle‐brush polymers, a class of polymers with serially grafted side‐chains, is challenging due to the interplay of side‐chain and backbone interactions over various length scales. The present work performs a detailed analysis, using molecular dynamics simulation techniques, to unravel these interactions by probing the distinct rod to a flexible real‐chain with self‐avoiding walk (SAW) type crossover in the backbone static structure factor. This analysis elucidates the deviation from flexible chain behavior, while also providing a quantitative measure of persistence length,l P . Significantly, the results identify a trend inl Pwhich is consistent with the debated theoretical prediction ofl P ∼ N s 15 / 8, where N s is the number of monomers in each side‐chain of the bottle‐brush polymer.
