Abstract

Poly-(beta-lactones) are made by reacting a 1:2-epoxide with carbon monoxide at a super-atmospheric pressure below about 500 atm., at a temperature below about 150 DEG C. and in the presence of a metal carbonyl as catalyst. Specified epoxides are ethylene-, propylene- and styrene-oxide. Suitable carbonyls are those of iron, cobalt, nickel or chromium. The yield may be increased by the presence of a metal halide (e.g. potassium iodide or mercuric chloride) or a quarternary ammonium halide. The tendency of the epoxides to polymerize may be diminished by adding a base (e.g. pyridine). Catalytic amounts of water, methanol or hydrogen which assist the formation of the carbonyl halide (a possible intermediate catalyst) may also be present.
