  • METHOD FOR PRODUCING POLYETHER KETONE KETONE AND POLYETHER KETONE KETONE PRODUCED THEREBY
    Publication number: 20230167241
    Abstract: A method for producing polyether ketone ketone at a high yield is disclosed. According to the method, a catalyst injection rate is controlled during production to suppress scale formation, whereby the yield can be improved. A polyether ketone ketone produced by the method is disclosed. The method makes it possible to maintain an intrinsic viscosity (IV) of the polymer without a significant change and adjust a particle size of polyether ketone ketone by preventing an aggregation between resin particles, thereby suppressing scale formation.
