Abstract Polyolefins are usually made in the form of particles, with the catalyst distributed inside these particles and monomers in gas or liq. form on the outside. Mass transfer restriction of monomers and other mols. into the polymer particles could be of significance. A method for studying this restriction is presented. The method is demonstrated on ethylene diffusion resistance in polyethylene preparation
