Reactive surfactants and their use in emulsions and dispersions

摘要

A reactive polymeric surfactant that contains: (a) at least two hydrophilic monomeric units per molecule, each independently according to formula (I): wherein R¹ is alkylene or oxyalkylene, R² is H, methyl, or ethyl, R³ is H, and n is greater than about 5, (b) one or more hydrophobic monomeric units per molecule, each independently according to formula (II) wherein R⁴ is H or methyl, R⁵ is a hydrophobic group, is useful in stabilizing aqueous emulsions and aqueous dispersions.
