Pseudo-bulk behaviour

Term · Chemistry · MLC-T-CHM-009631

A kinetic regime in emulsion, miniemulsion, microemulsion, suspension or dispersion polymerization in which the rate equations take the same form as in bulk polymerization, so each particle acts like a small bulk reactor. It applies for any average number of radicals per particle, from very high values to low values where radicals leave one particle and rapidly enter another. It concerns reaction kinetics, not the size of the particles.
