Dicyandiamide-epichlorohydrin polymer
[Preparation method] Synthesized with dicyandiamide and epichlorohydrin as raw materials, the specific reaction formula is:
Add epichlorohydrin and 50% sodium hydroxide solution to the reactor equipped with condensing reflux device, then add dicyandiamide and a small amount of initiator, raise the temperature of the system to 75~85℃, and replenish after 2~5h reaction Alkaline amount, and continue to raise the temperature to 95~110℃, after reacting for 3~4h, cooling to room temperature, the amphiphilic dicyandiamide epichlorohydrin polymer is obtained.
