Preparation of Copolymers of Carbon Monoxide and Olefinic Unsaturated Hydrocarbons (PREPARATION OF COPOLYMERS OF CARBON MORNOXIDE AND OLEFINICALLY UNSATURATED COMPOUNDS)

摘要

(A) Group VIII metal, (b) less than 2 pK_AAnd (c) an acid having the general formula R^OneR²P-R-P-R^OneR²Of bidentate (wherein R^OneAnd R²And R is a bivalent organic bridging group containing two or more carbon atoms in a bridge connecting two phosphorus atoms) in the presence of a catalyst system based on a copolymer of carbon monoxide and an olefinically unsaturated compound Characterized in that copolymerization is additionally carried out in the presence of hydrogen and the molar ratio of catalyst component (C) to catalyst component (a) is in the range 1-10.
