Polytrimethylene ether glycol or copolymers thereof having improved color and processes for their preparation |
| abstract |
Processes for reducing the color of polytrimethylene ether glycol or copolymers thereof are provided. The processes include polycondensing diols in the presence of an acid catalyst and adding base continuously over a period of the polycondensation reaction. The invention also relates to the polytrimethylene ether glycol thereof produced by these processes. |
