We consider both monodisperse systems and grand-canonical (Flory-distributed) equilibrium polymers. Density effects are discussed as well as finite chain length corrections. The intrachain bond-bond correlation function $P(r)$ is shown to decay as $P(r) \\sim 1/r^3$ for $\\xi \\ll r \\ll \\r^*$ with $\\xi$ ","authors_text":"A. Cavallo, A. Johner, H. Meyer, J.
