Abstract
Abstract Oleophobic and hydrophobic polymers are disclosed which are obtained from the polymerization of one or more fluorinated monomers with or without a minor amount of one or more nonfluorinated monomers in the presence of a nonfluorinated acrylic resin which represents from 20 to 80% by weight of the mixture of the monomer and resin. These polymers are useful for imparting oleophobic and hydrophobic properties to substrates such as textiles.

OLEPHOBIC AND HYDROPHOBIC POLYMERS OBTAINED FROM THE POLYMERIZATION OF ONE OR MORE POLYFLUROINATED SULFONAMIDOETHYLENE ACRYLATE OR METHACRYLATE MONOMERS IN THE PRESENCE OF A NONFLUORINATED ACRYLIC RESIN WHICH REPRESENTS FROM 20 TO 80% BY WEIGHT OF THE MONOMER AND RESIN AND WHEREIN THE FLUORINATED SULFONAMIDOETHYLENE MOIETY OF THE MONOMERS IS PRESENTED BY THE RADICAL
Claim 3
Dependent Claim
53 words
Oleophobic and hydrophobic polymers obtained from the polymerization of one or more polyfluorinated sulfonamidoethylene acrylate or methacrylate monomers in the presence of a nonfluorinated acrylic resin which represents from 20 to 80% by weight of the monomer and resin and wherein the fluorinated sulfonamidoethylene moiety of the monomers is presented by the radical
Claim 4
Dependent Claim
53 words
Oleophobic and hydrophobic polymers obtained from the polymerization of one or more polyfluorinated sulfonamidoethylene acrylate or methacrylate monomers in the presence of a nonfluorinated acrylic resin which represents from 20 to 80% by weight of the monomer and resin and wherein the fluorinated sulfonamidoethylene moiety of the monomers is presented by the radical
Claim 5
Dependent Claim
31 words
Oleophobic and hydrophobic polymers according to claim 1 wherein the fluorinated acrylate or methacrylate monomers are formed by reacting the alcohol of the fluorinated sulfonamidoethylene moiety with acrylic or methacrylic acid.
Claim 6
Dependent Claim
32 words

Claim 7
Dependent Claim
23 words
The method for rendering substrates hydrophobic and oleophobic which comprises employing an effective amount of at least one composition according to claim 1.
Claim 8
Dependent Claim
11 words
The method of claim 4 wherein the substrate is a textile.
