Abstract
Abstract Halogenated interpolymers of ethylene and carbon monoxide. The halogenated interpolymer is prepared by (a) preparing a mixture of a liquid medium and a backbone polymer having interpolymerized therein ethylene and carbon monoxide, (b) contacting the backbone polymer in the mixture with halogen at conditions effective to react the halogen only with carbon atoms in the alpha position with respect to the carbonyl groups in the backbone polymer, and (c) recovering the halogenated polymer of step (b). The halogenated interpolymer is useful in molding films and articles therefrom and as a plasticizer in polyvinyl chloride resins. In a preferred embodiment, the backbone polymer has a carbon monoxide content of about 8-20 wt. percent and the halogenated interpolymer has a halide content of about 10-24 wt. percent.
