abstract |
The present invention generally relates a polymer-metal junction comprising PEEK-PEmEK copolymers compositions, in contact with a metal substrate, wherein the PEEK-PEmEK copolymer having R PEEK and R PEmEK repeat units in a molar ratio R PEEK /R PEmEK ranging from 95/5 to 45/55. The present invention also relates to shaped articles including the polymer-metal junction, and methods of making the polymer-metal junctions. |
