Abstract
An improved process for the production of linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon employs a novel catalyst composition formed from a compound of palladium, the anion of a strong non-hydrohalogenic acid and a novel hexakis phosphine ligand. The process is characterized by a lessened degree of reactor fouling.
Claims8
A catalyst composition formed from a compound of palladium, the anion of a strong non-hydrohalogenic acid and a hexakis phosphine of the formula ##STR3## wherein R' independently is hydrogen or methyl and R independently is alkoxyphenyl wherein at least one alkoxy is a substituent on a ring carbon atom which is ortho to the ring carbon atom through which R is connected to phosphorus.
The composition of claim 3 wherein the anion is the anion of trifluoroacetic acid or p-toluenesulfonic acid.
