Title:
【発明の名称】耐熱性水分散性スルホポリエステル組成物
Document Type and Number:
Japanese Patent JP3369566
Kind Code:
B2
Abstract:
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 temperatures (Tg) of greater than 89 DEG 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.
