A new alternating block copolymer was synthesized from dihydroxy‐terminated poly‐(ether ketone sulfone) and bis(dimethylamino)‐terminated polydimethylsiloxane oligomers. The chemistry and the thermal properties are discussed. Surface chemical composition of films was analyzed by ESCA. Quantitative calculations showed a noticeable siloxane enrichment at the surface.
