BATON ROUGE, La. (AP) - A retired Dow Chemical Co. research scientist has been sentenced to five years in federal prison for his conviction on charges that he stole trade secrets from Dow's Plaquemine plant and sold them to companies in China.
The Advocate reports 75-year-old Wen Chyu Liu, also known as David Liou, was sentenced Wednesday U.S. District Judge James J. Brady.
Brady said he would hold a second hearing at a later date to determine how much restitution must be paid to Dow.
Prosecutors said Liu conspired with at least four other Dow employees in Louisiana and Germany to sell confidential information about the company's production of a polymer called chlorinated polyethylene, which is used in automotive hoses, vinyl siding and other products.
