Abstract

PURPOSE: To control the reaction of a synthetic resin by a method wherein the electrodes of a conductivity meter are inserted into the liquid of a synthetic resin feedstock, the reaction is allowed to proceed, the conductivity of reaction liquid is measured and the reaction is completed at the time at which M.W. produced resin shown a specified M.W.
CONSTITUTION: The reaction of a synthetic resin is controlled by a method wherein the electrodes of a conductivity meter are inserted into the liquid of the synthetic resin feedstock, the reaction is allowed to proceed, the conductivity of reaction liquid is measured, and the reaction is completed at the time at which the conductivity indicates that M.W. of produced resin is from 300W7000. Examples of the synthetic resins are satd. or unsaturated polyester, polyamide, polyether, phenol resin, etc. Preferred resins are those obtd. by condensation reaction. Heat-resistant conductivity meter, in which electrodes are not corroded by the reaction liquid, is preferred.
