| titleOfInvention | Process for the carbonylation polymerization of functionalized olefinically unsaturated compounds |
| abstract | A process for the preparation of polyesters or polyanhydrides comprises the reaction of: … … i) optionally substituted alkenols in which the hydroxy group is more than four carbon atoms remote from the nearest carbon atom participating in the double bond or of … ii) optionally substituted alkenoic acids in which the carboxyl group is more than three carbon atoms remote from the nearest carbon atom participating in the double bond, with carbon monoxide in the substantial absence of water and in the presence of a catalytic system which can be obtained by combining the following components: … … … a) a palladium (II) compound … b) a monodentate organic phosphine and/or organic arsine and/or organic stibine optionally mixed with a bidentate phosphine, arsine or stibine and … c) a protonic acid, having a pKa less than 2 (measured at 18 DEG C in an aqueous solution), in which the following conditions are fulfilled:… - the molar ratio of component(s) (b) per gram atom palladium is >/= 10, … - the molar ratio of component(s) (b) to component (c) is > 1 and… - the reaction temperature applied is < 140 DEG C. … |
