| titleOfInvention | Process for preparing polyketones |
| abstract | A process for preparing terpolymer polyketones comprises reacting at least two olefins with carbon monoxide at elevated temperature and pressure in the presence of a catalyst prepared from (a) a source of palladium, (b) a source of an anion which either does not coordinate with palladium or is less strongly coordinating to palladium than both carbon monoxide and the olefin(s) used and (c) a bisphosphine of formula (R¹)₂P-R-P(R¹)₂ wherein R¹ is an optionally polar substituted aromatic hydrocarbyl group and R is a divalent organic bridging group of formula -(CH₂) n - where n = 2 to 8 and (d) a 1,4 quinone. The process is characterised by being carried out in a solvent comprising a mixture of an aprotic polar solvent and from 0.0001 to 0.5% by weight water. The particular solvent system used is especially useful for preparing terpolymer polyketones of high molecular weight. |
