Disclosed is a method for preparing fluorinated emulsion polymers that reduces or eliminates the need for fluorinated surfactants comprising the steps of: a) providing a reaction mixture comprising water, surfactant, monomer mixture comprising at least one fluorinated monomer, at least one non-fluorinated monomer having high water solubility, and optionally at least one non-fluorinated monomer having low water solubility, macromolecular organic compound having a hydrophobic cavity; and b) polymerizing said monomer mixture.
The present invention provides compositions that feature improved preferential adhesion and release characteristics with respect to a substrate and a mold having imprinting material disposed therebetween. To that end, the compositions facilitate bifurcation of the imprinting into a surfactant-component-rich sub-portion and a surfactant-component-depleted sub-portion located between said surfactant-component-rich sub-portion and said substrate. This surfactant-component-rich sub-portion attenuates the adhesion forces between the mold and the imprinting material, once solidified.
