Retired Dow Chemical employee sent to federal prison for selling secrets to China

A retired Dow Chemical Co. research scientist has been sentenced to five years in federal prison for selling to Chinese companies trade secrets he gained while working at Dow's Plaquemine, La. plant. A report from The Advocate said 75-year-old Wen Chyu Liu, also known as David Liou, sold the firm's secrets on the patent for production of Tyrin CPE, a chlorinated polyethylene polymer used in vinyl siding, plastic jackets for electrical wire, flexible automotive and industrial hoses, as well as other products for about $600,000. Liu on Wednesday was sentenced to five years in federal prison. Two other men pleaded guilty to related charges in the case and testified against Liu. Both were sentenced to probation.
