METHOD FOR PURIFICATION OF ETHYL-2-CYANOACRYLATE ADHESIVE COMPOSITION, AND ETHYL-2-CYANOACRYLATE ADHESIVE COMPOSITION

摘要

Provided is an ethyl-2-cyanoacryalte adhesive composition which is remarkably improved in terms of irritating odor generation and whitening in comparison to conventional ethyl-2- cyanoacrylate adhesives (which suffer from problematic irritating odor generation and whitening). Also provided is a method for the purification of an ethyl-2-cyanoacrylate adhesive composition which comprises deaerating an ethyl-2 -cyanoacrylate adhesive composition while blowing an inert gas thereinto under a reduced pressure of 100 to 10000Pa at a temperature of 5 to 50°C to lower the total content of acrylonitrile and ethanol to a level of 1 to 150ppm. Thus, the method can achieve an improvement in terms of irritating odor generation and whitening.
