The 50/50 joint venture between Styron and Sumitomo Chemical is being renamed Sumika Styron Polycarbonate Limited (SSPC). Company name change activities are underway and are expected to be fully effective as of April 1. Styron announced in October that it assumed ownership of the 50% share that was formerly owned by The Dow Chemical Company, following Dow's divestiture of Styron to Bain Capital Partners in June 2010.

The joint venture will continue to be headquartered in Tokyo, and will continue to serve its customers and market polycarbonate products in Asia Pacific.
