Abstract

Linear, alternating .alpha.-olefin-CO copolymers are obtainable by polymerization of a monomer mixture comprising PA1 a) carbon monoxide, PA1 b) 1-alkenes which are functionalized by a covalently bonded crown ether unit or cryptand unit A containing at least 5 heteroatoms selected from the group consisting of nitrogen, oxygen, sulfur and/or selenium in the polyheteroatom framework, and, if desired, PA1 c) C.sub.2 -C.sub.24 -1-alkenes.
