COPOLYMERS FOR STAIN RESISTANCE
Method for imparting stain resistance to a substrate comprising contacting the substrate with a copolymer comprising Formula 1. wherein D is an aryl olefin, alpha olefin or diene, each M is independently H, Ca, Mg<SUB>1</SUB> Al, Na, or K, each R<SUB>1</SUB> is independently H, C<SUB>1</SUB> - C<SUB>6</SUB> alkyl, or C<SUB>1</SUB> - C<SUB>6</SUB> hydroxyalkyl, each R<SUB>2</SUB> is independently C<SUB>1</SUB> - C<SUB>12</SUB> alkyl, C<SUB>1</SUB> - C<SUB>6</SUB> hydroxyalkyl, C<SUB>6</SUB>F<SUB>5</SUB>, arylalkyl, C<SUB>6</SUB>H<SUB>4</SUB>OH, R<SUB>3</SUB>COOH<SUB>1</SUB> or R<SUB>3</SUB>SO<SUB>3</SUB>H<SUB>1</SUB> or R<SUB>1</SUB> and R<SUB>2</SUB> are linked together to form a morpholino or pyrrolidino ring, R<SUB>3</SUB> is C<SUB>1</SUB> - C<SUB>12</SUB> alkyl, CH(COOH)CH<SUB>2</SUB>CH<SUB>2</SUB>, C<SUB>6</SUB>H<SUB>4</SUB>, or C<SUB>6</SUB>H<SUB>3</SUB>(OH), h<SUB>1</SUB> + h<SUB>2</SUB> is h, h is a positive integer, k, i and j are each independently zero or a positive integer, provided that the total of 1) h oe(k + h + i + j) is 0.005 to 0.7, 2) k oe(k + h + i + j) is 0.3 to 0.6, and 3) [i + j] oe(k + h + i + j) is 0 to 0.6.
