Patent number: 6534602Abstract: A process for reducing the carbonyl group of a polyketone consisting of a carbon monoxide ethylene-based copolymer, comprising reacting a blend of carbon monoxide ethylene-based polymer with a metal alkoxide in a molten condition in proportions to provide a novel polyalcohol. This chemical modification changes the properties of the carbon monoxide ethylene-based polymers and renders them eligible for uses for which the original polymers were not or not very suitable.Type: GrantFiled: August 16, 1999Date of Patent: March 18, 2003Assignee: E. I. du Pont de Nemours and CompanyInventors: George Henry Hofmann, Sampson Chun Fai Lee
