(Adds details on expansion between paragraphs 2 and 4)
Sept 19 (Reuters) - Exxon Mobil said on Tuesday it has started two new chemical production units at its Baytown, Texas refining and petrochemical complex.
The company said the $2 billion expansion is part of its long-term plan to deliver higher-value products from its U.S. Gulf Coast facilities.
One of the two new units is expected to produce 400,000 metric tons per year of certain polymer modifiers, utilized in automotive parts, construction materials and hygiene and personal care products.
The other unit would produce 350,000 tons per year of a type of compound called linear alpha olefins used in plastic packaging, engine and industrial oils and other applications.
