B01J 37/00

US Classification:

502102, 528405, 528412, 528480, 502104

Abstract:

The present invention provides unimolecular metal complexes having increased activity in the copolymerization of carbon dioxide and epoxides. Also provided are methods of using such metal complexes in the synthesis of polymers. According to one aspect, the present invention provides metal complexes comprising an activating species with co-catalytic activity tethered to a multidentate ligand that is coordinated to the active metal center of the complex.

Abstract:

In one aspect, the present invention encompasses integrated processes for the conversion of epoxides to acrylic acid derivatives and polyesters. In certain embodiments, the methods of the present invention comprise the steps of: providing a feedstock stream comprising an epoxide and carbon monoxide; contacting the feedstock stream with a metal carbonyl in a first reaction zone to effect conversion of at least a portion of the provided epoxide to a beta lactone; directing the effluent from the first reaction zone to a second reaction zone where the beta lactone is subjected to conditions that convert it to a compound selected from the group consisting of: an alpha beta unsaturated acid, an alpha beta unsaturated ester, an alpha beta unsaturated amide, and an optionally substituted polypropiolactone polymer; and isolating a final product comprising the alpha-beta unsaturated carboxylic acid, the alpha-beta unsaturated ester, the alpha-beta unsaturated amide or the polypropiolactone.
