| Zusammenfassung: | The present invention is a process for making poly(ethylene-co-isosorbide) terephthalate polymer that has low color and low diethylene glycol (DEG) content.
The present invention is a process for making a low color copolymer of ethylene glycol, isosorbide and terephthalic acid or dimethyl terephthalate. This copolymer, poly(ethylene-co-isosorbide) terephthalate, is useful for making bottles, hot-fill containers, films, sheet, fiber, strand and optical article applications. It can also be used to make polymer blends and alloys. |
