ABSTRACT:
This invention relates to compounds of formula:wherein A is an unsaturated alkylene moiety; B the residue of a polyol wherein one hydroxyl moiety is esterified with one carboxyl moiety of the phthalic acid moiety; D is the residue of a polyol wherein one hydroxyl moiety is esterified with another carboxyl moiety of the phthalic acid moiety, and another hydroxyl moiety is esterified with one carboxyl moiety of the unsaturated alkylene moiety; E is the residue of polyol wherein one hydroxyl moiety is esterified with another carboxyl moiety of the unsaturated alkylene moiety; and M is a cation. The compounds can be used alone, or polymerized, or polymerized and combined with other polymers, to form effective stain and soil repellent compositions.
