Abstract
Amorphous copolyesters containing residues derived from 2,2′-[2,2-](sulfonylbis(4,1-phenyleneoxy))bis(ethanol). They exhibit enhanced heat distortion temperatures and glass transition temperatures without a significant increase in viscosity at low shear rates. The amorphous copolyesters also have improved resistance to attack by lipid solutions and are readily molded and extruded to form medial devices such as connectors, tubes, etc. which are useful for transport of lipids and other medical solutions.
