Abstract

PURPOSE: To detect the starting point of emulsion polymerization reaction or a like, by passing a light beam from a light source via an optical fiber through a polymerization reaction system and measuring the scattered light from the polymer.
CONSTITUTION: The light emitted from a light source 21 is converged through a converging lens 22 and the light beam is introduced via an optical fiber 23 into the measurement point 25 within a polymerization reactor. The scattered light is introduced via an optical fiber 23 into a light-receiving element 24 by which the strength of the scattered light from the polymer formed by the initiation of polymerization is measured, and the output of the element 24 is recorded.
EFFECT: The detector can detect not only the static dispersion state of a dispersion but also the change in concentration in the course of the reaction or the change in concentration of a dispersed phase with a definite particle diameter.
