ABSTRACT:
A polyketone is provided wherein the polyketone is water soluble and curable. A method to make a such a polymer is also disclosed, the method including the steps of: providing a polyketone, the polyketone comprising 1,4-diketone units; contacting the polyketone with a diamine wherein the diamine comprises one nitrogen which is more reactive than another of the nitrogens under conditions effective to incorporate the more reactive nitrogen in the polyketone; contacting the polyketone having the diamine incorporated into the polyketone with maleic anhydride under conditions effective to react the less reactive nitrogen with the maleic anhydride; contacting the polyketone having maleic anhydride incorporated thereto with a strong base; and recovering a functionalized polyketone wherein the functionalized polyketone is water soluble and curable.
