Document Type and Number:
WIPO Patent Application WO/2016/080656
Kind Code:
A1
Abstract:
The present invention relates to a method for producing polyketone, the method comprising: a gas-phase polymerization method which can increase output of polyketone; a solid-phase catalyst for polyketone polymerization which does not use any carrier, and a production method therefor; a method for, in a slurry polymerization process, precipitating palladium in a solid phase and thus easily recovering the same; a production method having excellent anti-oxidation, heat stability, and UV blocking effects, even using a small amount of additives; a method for producing low melting point polyketone, characterized by inputting a hydride anion donor; and basic process technology for recovering noble metal palladium from waste discharged in a polyketone polymerization process.
