Sulfonate group-containing substance and preparation method and application thereof |
| abstract |
The application discloses a substance containing sulfonate groups, a preparation method and application thereof. The molecular chain of the substance comprises an isophthalic acid-5-sulfonate unit, a terephthalic acid unit and a dihydric alcohol unit; the number average molecular weight of the substance is 600 to 2000 g/mol. The sulfonate group-containing substance has good compatibility with polyester, less filtration pressure rise in subsequent polyester melt spinning, long replacement period of a filter screen in spinning engineering and low cost. |
