POLYMERIZABLE COMPOUNDS AND USES THEREOF

摘要

Polymerizable ester surfactant, or a salt thereof, having a formula: R<1>-C(O)-R<2>-X wherein: R<1> is an optionally substituted vinyl radical, R<2> 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 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 diphosphate 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.
