Abstract
A method for forming a fiber is provided. The method comprises supplying at least one aromatic polyester to a melt processing device and modifying the aromatic polyester with at least one polyether copolymer within the device to form a thermoplastic composition having a melt flow rate that is greater than the melt flow rate of the aromatic polyester. The polyether copolymer contains a repeating unit (A) having the following formula:C2H4Ox (A)wherein,
