Title:
HIGH-STRENGTH AND LOW-CHROMA POLYETHER ETHER KETONE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/016487
Kind Code:
A1
Abstract:
A high-strength and low-chroma polyether ether ketone and a preparation method therefor. The method comprises the following steps: subjecting a first polymeric monomer and a second polymeric monomer to a nucleophilic polycondensation reaction in an inert aprotic solvent in the presence of alkali carbonate under the pressure of 0.15 MPa to 1.0 MPa in an inert atmosphere to obtain polyether ether ketone. The reaction time can be shortened, the reaction temperature can be lowered, and energy and cost can be reduced; moreover, the impact strength of the polymer is improved, and the color is brighter and whiter.
