The claimants in a case against four chemical companies, Evonik Degussa Corp., Lucite International Inc., Arkema Inc. and Imperial Chemical Industries Limited, have requested a judge in the US District Court for the Eastern District of Pennsylvania to approve four settlement agreements following negotiations with the companies. If the settlement is approved, the money will be placed in escrow, and direct purchasers of methyl methacrylate and acrylic will be able to reclaim some or all of the money paid for purchases between 1 January 1995 and 19 December 2007.
