  • Polyesters and polyester containers having a reduced coefficient of friction and improved clarity
    Patent number: 7399802
    Abstract: Polyesters and polyester containers having a reduced coefficient of friction and improved clarity are produced using an antiblock agent comprising a dried talc having from about 20 to about 300 ppm water or a fatty acid tethered talc. The use of these talcs result in polyesters and polyester containers having a coefficient of less than about 1.0 and a clarity with haze values of less than about 4%.
    Type: Grant
    Filed: March 17, 2005
    Date of Patent: July 15, 2008
    Assignee: Eastman Chemical Company
    Inventors: Steven Lee Stafford, Ronald Richard Light, Louis Thomas Germinario, Emerson Eston Sharpe, Jr.
