CATALYST COMPOSITIONS AND PROCESS FOR OLEFIN/CO COPOLYMERIZATION

摘要

T 105 NOVEL CATALYST COMPOSITIONS AND PROCESS FOR OLEFIN/CO-COPOLYMERIZATION Novel catalyst compositions, characterized in that they are based upon a) a palladium compound, b) an anion of an acid with a pKa of less than 2, with the proviso that the acid is not a hydrohalogenic acid, and c) a compound in which there occur one phosphorus atom and one or more nitrogen atoms which atoms bear no hydrogen, and in which compound each one of the nitrogen atoms is connected to the phosphorus atom by an organic bridging group which contains at least one carbon atom in the bridge.
