Beschreibung
Zusammenfassung:	A copolymer compositions comprising a major amount of an alternating copolymer of carbon monoxide with one or more olefinically unsaturated compounds and a minor of at least one stabilizing additive which is a zeolite-type trivalent-metal silicate containing a cation of an element of Group 2 of the Periodic Table is disclosed. This copolymer composition has and exhibits improved stability and contains a substantially reduced amount of residual solvent. Also disclosed is a process for producing this copolymer composition, and articles of manufacture made from this composition.
