Compositeness conditions for particle poles in partial wave scattering amplitudes are studied with particular regard to various dynamical limits connected with a continuous transition from elementary to composite particles. The first part is concerned mainly with some simple, but non‐trivial models whereas in the second part the present considerations are generalized and also the question of analytic continuation in the angular momentum and the manychannel case is treated.
