Poly ( tetramethylene terephthalate ) - polyether block copolymers |
| abstract |
ABSTRACT OF THE DISCLOSURE Poly (tetramethylene terephthalate)-polyether block copolymers having materially increased heat deflection temperatures and incorporating within the polymer chain in random distribution 1 percent to 7 percent by weight of the polyether, poly(tetramethylene ether glycol) or polyethylene oxide; the polyether being added to the reaction mixture in the course of the polymerization reaction. |
