Abstract
The present invention relates to associative complexes of water soluble and/or water dispersible polymers and polymeric fluorosurfactants, compositions and methods for modifying substrates to provide treated articles with surface protective properties including easier cleaning, increased stain and/or soil repellency, and increased resistance to bio-fouling and environmental contamination.

A composition comprising:
- a. an associative complex comprising:
- i. a water soluble and/or water dispersible polymer;
- ii. at least one polymeric fluorosurfactant capable of forming an associative complex with said polymer, wherein said polymeric fluorosurfactant comprises a fluorosurfactant derived from polymerization of a fluorinated oxetane;
- b. optionally, a dispersant, and;
- c. optionally, a liquid carrier,
- wherein the associative complex forms an invisible film upon a surface of a substrate wherein said film is less than 500 nanometers in average thickness;
- wherein the associative complex molar ratio parameter, R, is greater than 0 to about 20, and wherein said associative complex is selected from the group consisting of
- I) (A) said polymer comprising a polar and/or polarizable first constituent capable of forming a hydrogen bond;
- and
- (B) said polymeric fluorosurfactant comprising a polar and/or polarizable second constituent capable of forming a hydrogen bond with said first constituent;
- and
- II) (A) said polymer comprising a charged and/or polarizable third constituent and at least one polar and/or polarizable fourth constituent capable of forming a hydrogen bond;
- and
- (B) said polymeric fluorosurfactant comprising a charged/and or polarizable fifth constituent and at least one polar and/or polarizable sixth constitutuent capable of forming a hydrogen bond with said fourth constituent;
- wherein said fifth constituent bears a charge opposite to that of said third constituent.

A method for preparing a treated article comprising the steps of:
- 1. providing a substrate;
- and
- 2. applying to at least one surface of said substrate a treatment composition that comprises:
- (a) an associative complex comprising:
- i. a water soluble and/or water dispersible polymer;
- ii. at least one polymeric fluorosurfactant wherein said polymeric fluorosurfactant comprises a fluorosurfactant derived from polymerization of a fluorinated oxetane and is selected from the group consisting of neutral, anionic, cationic, zwitterionic and/or ionizable fluorinated polymeric surfactants, and/or mixtures thereof, wherein said fluorosurfactant forms an associative complex with said polymer;
- (b) optionally, a dispersant, and;
- (c) optionally, a liquid carrier;
- and
- 3. removing said treatment composition from said substrate to leave a treated article
- whereby said associative complex is deposited on said surface of said substrate;
- wherein the associative complex forms an invisible film upon said surface of said substrate wherein said film is less than 500 nanometers in average thickness;
- wherein the associative complex molar ratio parameter, R, is greater than 0 to about 20.0;
- and wherein said associative complex is selected from the group consisting of
- I) (A) said polymer comprising a polar and/or polarizable first constituent capable of forming a hydrogen bond;
- and
- (B) said polymeric fluorosurfactant comprising a polar and/or polarizable second constituent capable of forming a hydrogen bond with said first constituent;
- and
- II) (A) said polymer comprising a charged and/or polarizable third constituent and at least one polar and/or polarizable fourth constituent capable of forming a hydrogen bond;
- and
- (B) said polymeric fluorosurfactant comprising a charged/and or polarizable fifth constituent and at least one polar and/or polarizable sixth constitutuent capable of forming a hydrogen bond with said fourth constituent;
- wherein said fifth constituent bears a charge opposite to that of said third constituent.
