Abstract (en)

[origin: DE19714031A1] The invention concerns linear alternating alpha -olefin/CO-copolymers obtained by polymerizing a monomer mixture that contains: a) carbon monoxide; b) 1-alkenes which are functionalized in the polyheteroatom structure with a covalently bonded crown ether or cryptand unit A containing at least 5 heteroatoms selected from the group comprising nitrogen, oxygen, sulphur and/or selenium; and optionally c) C2 to C24 1-alkenes.
