  • Reduction of glycol ethers in polyesters
    Patent number: 4230818
    Abstract: A process for reducing the glycol ether content in polyesters involves adding a glycol to a polyester oligomer solution prior to polymerization, distilling the oligomer solution to remove vapor containing the glycol as well as the glycol ether, and polymerizing the solution to produce a polyester containing a reduced glycol ether content.
    Type: Grant
    Filed: March 1, 1979
    Date of Patent: October 28, 1980
    Assignee: The Goodyear Tire & Rubber Company
    Inventors: Roy M. Broughton, Jr., Douglas D. Callander, Brian W. Pengilly, Joseph P. Schirmer, Terence E. Winters
  • Method for producing polyesters containing low amounts of ether by-products
    Patent number: 4223124
    Abstract: A method for decreasing the amount of ether as a by-product in polyesters (for example terephthalic-based) by initially utilizing a deficient amount of a glycol (for example, ethylene glycol) in the early reaction stages and utilizing an excess of the glycol in the final or end stages. The polyesters produced are of better quality, have a high melting point, possess increased thermal stability, and yield improved fiber properties.
