DuPont said it is seeking buyers for two separate businesses, a polyester-film joint venture and one that makes powder-based paint. According to a Bloomberg report, DuPont is also considering buying the 28% stake it doesn't already own in Solae, its soy-products joint venture with Bunge. It added that DuPont has put that process on hold while it decides whether to merge the business with Danisco, a Danish-based maker of food ingredients and enzymes.
