  • Polymerizable compounds and use thereof
    Patent number: 6534597
    Abstract: Polymerizable ester surfactant, or a salt thereof, having the formula: R1—C(O)—R2—X wherein: R1 is an optionally substituted vinyl radical, R2 is a divalent polyoxyalkylene radical having at least two oxypropylene units, optional oxyethylene units in a block or random pattern, and a molar ratio oxypropylene units to oxyethylene units of at least about 2:1, preferably at least about 3:1, typically at least about 4:1 and more typically at least about 5:1, and X is a phosphate group, wherein in the ester the mono-phosphate ester to di-phosphate ester weight ratio is greater than 80:20. These polymerizable surfactant compounds are useful as the sole surfactant in producing polymer latices by emulsion polymerization by polymerization of them with another polymerizable monomer.
