Abstract Videomicroscopy as a tool for investigating olefin gas phase co‐polymerization is presented in this paper. This technique enables the simultaneous detection of the individual growth of a large number of catalyst particles. The focus is to study the kinetic behaviour of different types of Ziegler‐ and metallocene catalysts and to demonstrate that videomicroscopy can help to assign a given catalyst system to the appropriate model. Further, the density problem, the estimation of activation energies of single grains, the particle volume enlargement of amorphous copolymers and the comonomer effect are adressed.
