MIDLAND, Mich. — The Dow Chemical Co. completed its $7.3-billion acquisition of Union Carbide Corp., Danbury, Conn., after agreeing to a Federal Trade Commission (FTC) stipulation that Dow must divest intellectual property related to the production of plastic trash bags.

In the stock transaction, Union Carbide becomes a wholly owned subsidiary of Dow, which will remain headquartered in Midland, Mich.

The merger creates the second-biggest U.S. chemical company, behind DuPont. Dow is a major supplier of raw materials, including epoxy and latex resins, solvents, acrylic monomers, polyurethane resins, and a variety of additives.

Huntsman said the acquisition provides a complement to the company’s existing amines business and expands its global polyurethanes business by adding polyol and urethane-catalyst production.
