Polyketone related polymers.

摘要

Polyketone related polymers, characterized in that they consist of linear chains in which units A and units B occur in alternating order, that the units A are the same or different optionally mono-alkyl-substituted ethylene groups and that the units B are the same or different optionally 3-alkyl-substituted 2,5-tetrahydrofurandiyl groups. They may be prepared from linear alternating polyketones by hydrogenation in the presence of a complex ruthenium catalyst.
