Abstract

The invention discloses a polyetheretherketone ketone resin and synthesizing method with diphenylbenzene phosphor as structure (I, II, III), which is characterized by the following: affirming the polymer as object product through infrared spectrum and nuclear magnetic resonance; reacting FPPPO and bisphenol A (BPA), bisphenol S (BPS) and hydroquinone (HQ) to synthesize three polyaryletheretherketone resins with diphenylbenzene phosphor structure.

Description

technical field [0001] The invention relates to the synthesis of a novel soluble high-temperature-resistant polyether ether ketone ketone resin, which belongs to the field of synthesis of special engineering plastics. Background technique [0002] With the development of polymer science, new polymer materials emerge in an endless stream. Special engineering plastic polyaryletherketone is one of them. Polyaryletherketone has been widely used in aerospace, electronics, information, nuclear energy and military fields due to its excellent heat resistance, radiation resistance, chemical stability, dielectric properties and outstanding mechanical properties. [0003] Structurally, polyaryletherketone is a kind of aromatic ring polymer containing ether bond and carbonyl group. It was the British ICI company that first engaged in the research of polyarylether ketone and put it into industrial production abroad. ICI company began to develop it in 1962, successfully developed it in...
