摘要：
The polyester-polyethers of the present invention are block copolymers wherein the polyester component may be crystalline or amorphous, while the polyether component is comprised of a polyethylene glycol having a molecular weight from about 990 to 3600 g/mole. Optionally, salts of 5-sulfoisophthalic acid (5-SIPA) may be included in the polyester component for superior static dissipative performance. Low levels of 5-SIPA, 0.05 - 5 mole%, are surprisingly effective at enhancing static dissipative performance. One aspect of this invention relates to antistatic blends having very low ionic extractables.
