Functionalized polyaryletherketones

摘要

Bromomethyl derivatives of polyaryl ether ketones are obtained by brominating methyl derivatives of the ketones preferably with elemental bromine, optionally under UV light. The bromomethyl derivatives are useful as intermediates for further functionalization of the aromatic polyether ketones. The functionalized derivatives, depending on the substituent, exhibit different properties than the basic polymer, for example increased hydrophilicity and solubility.
