Styron Said to Plan IPO Less Than 9 Months After Bain Buyout

Styron Corp. is planning an initial public offering less than nine months after Bain Capital LLC bought the company from Dow Chemical Co. for $1.63 billion, said two people with knowledge of the matter.

Banks are being interviewed to handle a share sale, said the people, who spoke on the condition of anonymity because the talks are private. Dow Chemical, based in Midland, Michigan, still has a 7.5 percent stake in Styron, the world’s largest producer of polystyrene.
