  • Method for preparing copolyester-ether film
    Patent number: 9234076
    Abstract: A method for preparing a copolyester-ether film is provided, wherein the method includes a recycled polyester is provided. Alcoholysis is performed by reacting the recycled polyester with a diol to form a first intermediate, wherein the molar ratio of the recycled polyester to the diol is 1:1.8-2.5. Transesterification is performed to the first intermediate to form a second intermediate, wherein the temperature of transesterification is between 190° C. and 230° C. A polyol is added to the second intermediate and polymerization is performed to form a copolyester-ether, wherein the weight percent of the polyol in the copolyester-ether is 24-55%. The copolyester-ether is manufactured into a flexible film.
