Polyethylene teraphthalate and uses thereof.

摘要

Polyethylene terephthalates having 97 to 98.6 mole % of repeating ethylene terephthalate units and 3 to 1.4 mole % of repeating units of diethyleneoxy terephthalate units have excellent mechanical strength, heat resistance and transparency, and can be used to provide blow molded containers of excellent high temperature filling properties such that they can be filled at high temperature without deforming and can be sterilized.
