titleOfInvention | Process for the preparation of polyketones. |
abstract | A process for preparing a polyketone is described. This process consists in copolymerizing carbon monoxide, ethylene and optionally at least one C3 to C10 alpha-olefin in the presence of a solvent and of a catalyst composition which can be derived from a salt of palladium, of an anion capable of being weakly coordinated or which is not coordinated with respect to palladium, and of a phosphine ligand, the solvent being composed either of a tertiary C4 to C10 aliphatic alcohol or of a mixture of a C4 to C10 tertiary alcohol and up to 80% by volume of a proton-free solvent. Preferred tertiary alcohols are tertiary alcohol and tertiary amyl alcohol. Proton-free solvents may consist of an aliphatic ketone or a cyclic aliphatic ether, preferred proton-free solvents are tetrahydrofuran and 1,4-dioxane. |
