Claims
- 1. A supported catalyst composition, useful in the production of linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon, which catalyst composition comprises (a) a compound of palladium, (b) the anion of a nonhydrohalogenic acid having a pKa of below about 4 and (c) a bidentate ligand of phosphorus wherein the ligand is bound through reactive functional groups of the ligand to reactive functional groups of the catalyst composition support and the catalyst composition support particles have an average particle diameter of at least 500 .mu..
- 2. The composition of claim 1 wherein the compound of palladium is palladium acetate.
- 3. The composition of claim 2 wherein the strong acid has a pKa below 2.
- 4. The composition of claim 3 wherein the reactive functional groups of the ligand are selected from the group consisting of hydroxyl and trialkoxysilyl.
- 5. The composition of claim 4 wherein the reactive functional groups of the support are selected from the group consisting of carbonyl, hydroxyl, carboxyl, halogen and isocyanate.
- 6. The composition of claim 2 wherein the carrier is silica or silica-alumina.
- 7. The composition of claim 6 wherein the ligand is 2-hydroxy-1,3-bis[di(2-methoxyphenyl)phosphino]propane or 7-di(2-methoxyphenyl)phosphinomethyl-8-di(2-methoxyphenyl)phosphinooctanol-1.
- 8. The composition of claim 7 wherein the anion is the anion of trifluoroacetic acid or p-toluenesulfonic acid.
- 9. The composition of claim 8 wherein the support is silica.
