Abstract
Abstract Polymers of carbon monoxide and one or more olefinically unsaturated compounds are prepared by contacting with a catalyst composition comprising a Group VIII metal and a compound of the general formula R¹M¹-R-M²R² wherein M¹ and M² are chosen from sulphur, selenium and tellurium, R¹ and R² represent optionally polar-substituted hydrocarbyl groups and R represents a bivalent bridging group containing at least two carbon atoms in the bridge.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
94 words
Process for the preparation of polymers, characterized in that a mixture of carbon monoxide with one or more olefinically unsaturated compounds is contacted at elevated temperature and pressure with a catalyst composition comprising a Group VIII metal and a compound of the general formula R¹M¹-R-M²R², wherein M¹ and M² are the same or different elements chosen from the group made up of sulphur, selenium and tellurium, R¹ and R² are the same or different, optionally polar-substituted, hydrocarbyl groups and R represents a bivalent bridging group containing at least two carbon atoms in the bridge.
Claim 2
Dependent Claim
