METHOD METHOD AND DEVICE FOR CONTINUOUSLY MEASURING CHANGE IN RHEOLOGICAL PROPERTY OF MONOMER DURING POLYMERIZATION

Document Type and Number:

Japanese Patent JPS5547449

Kind Code:

A

Abstract:

Method of and apparatus for the continuous measurement of changes in rheological properties of monomers during polymerization. Longitudinal ultrasonic oscillations are introduced into the polymerizing system, and oscillations received after passage through a part of the polymerization system are monitored as the polymerization process proceeds. The ultrasonic oscillations have a frequency of 0.02 to 100 MHz. The monitoring may be of the absorption of the oscillations and/or the rate of propagation of the oscillations.
