METHOD FOR PREPARING POLY ETHER KETONE KETONE AND POLY ETHER KETONE KETONE THEREFROM

摘要

The present invention relates to a method for producing a polyether ketone ketone that can improve the yield by suppressing scale formation by controlling the catalyst input rate during production, and more specifically, maintaining the value of Inherent Viscosity (IV) without significantly changing The method of manufacturing polyether ketone ketones capable of obtaining a high molecular weight polyether ketone ketone with a high yield, preferably a value of 90% or more, and preventing particle aggregation between resin particles by suppressing scale generation, and It relates to the polyether ketone ketone produced thereby.
