Fibers Formed from Aromatic Polyester and Polyether Copolymer

摘要

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:;;wherein,
x is an integer from 1 to 250,a the polyether copolymer further containing a repeating unit (B) having the following formula:;;wherein,
n is an integer from 3 to 20; andy is an integer from 1 to 150.
