Abstract
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.
Claims7
A method for preparing a fluorinated emulsion polymer comprising, as polymerized units, at least one fluorinated monomer and at least one non-fluorinated monomer having high water solubility, comprising the steps of:
- a) providing a reaction mixture comprising
- i) water,
- ii) surfactant,
- iii) monomer mixture comprising from 1 to 99 percent by weight of at least one fluorinated monomer, from 1 to 10 percent by weight of at least one non-fluorinated monomer having high water solubility, and from 0 to 98 percent by weight of at least one non-fluorinated monomer having low water solubility,
- iv) macromolecular organic compound selected from the group consisting of cyclodextrin;
- cyclodextrin derivatives;
- cycloinulohexose;
- cycloinuloheptose;
- cycloinuloctose;
- calyxarene and cavitand;
- and
