Polymerizable fluorochemical surfactants

摘要

Polymerizable, organic-soluble, oligomeric fluorochemical surfactant compositions having at least two pendent fluoroaliphatic groups, at least two organic-solubilizing groups, and a pendent polymerizable olefinic group. Also a method of preparing such surfactant compositions. The compositions reduce the surface energy of acrylate-containing mixtures and acrylate-based pressure-sensitive adhesives. They can be used in preparing acrylate-based pressure-sensitive adhesives that coat well due to the presence of the surfactant and maintain adhesive performance upon aging.
