HEAT-RESISTANT WATER-DISPERSIBLE SULFOPOLYESTER COMPOSITIONS |
摘要 |
The present invention relates to sulfonate containing water-dispersible or water-dissipatible sulfopolyester compositions. The sulfopolyesters utilize at least two dicarboxylic acids, one of which is a naphthalene dicarboxylic acid. This combination of dicarboxylic acids allows for the sulfopolyesters to maintain glass transition temperature (Tg) of greater than 89 .degree.C and exhibit lower melt viscosities than sulfopolyesters containing all naphthalenediyl units or all isophthtaloyl units. The sulfopolyesters of this invention are useful in applications where improved heat and blocking resistance is required.
