Claims
- 1. A stain-resistant polyamide textile substrate having deposited on it, in an amont effective to impart resistance to staining by acid dyes, a composition comprising a polymer containing between about one and two polymer units derived from one or more ethylenically unsaturated aromatic monomers per polymer unit derived from maleic anhdridge, which has been hydrolyzed in the presence of an alkali metal hydroxide or ammonium hydroxide and which has a number average molecular weight in the range between about 500 and 4000, said stain-resistant substrate which has said composition deposited on it being suitable for immediate use in carpeting, upholstery fabric, or the like.
- 2. The substrate of claim 1 wherein said amount is between 0.1 and 2% by weight and said ethylenically unsaturated aromatic monomer can be represented by the formula ##STR5## where R is ##STR6## R.sup.1 is H--, CH.sub.3 ; or ##STR7## R.sup.2 is H--or CH.sub.3 --; R.sup.3 is H--or CH.sub.3 O--;
- R.sup.4 is H--, CH.sub.3 --; or ##STR8## R.sup.3 plus R.sup.4 is --O--CH.sub.2 --O--.
- 3. The substrate of claim 1 wherein said ethylenically unsaturated aromatic monomer is styrene.
- 4. The substrate of claim 1 wherein said polymer contains about one polymer unit derived from maleic anhydride per polymer unit derived from one or more ethylenically unsaturated aromatic monomers.
- 5. The substrate of claim 1 wherein said polymer contains about one polymer unit derived from maleic anhydride per polymer unit derived from styrene.
- 6. The substrate of claim 1 wherein said polymer has been hydrolyzed in the presence of sodium hydroxide.
- 7. The substrate of claim 6 wherein said polymer contains about one polymer unit derived from maleic anhydride per polymer unit derived from styrene.
- 8. A process for imparting stain-resistance to a textile subsrate which comprises applying to said substrate, in an amount effective to impart to said substrate resistance to the staining effects of acid dyes, a composition comprising a polymer containing between about one and two polymer units derived from one or more vinyl-aromatic monomes per polymer unit derived from maleic anhydride, which has been hydrolyzed in the presence of an alkali metal hydroxide or ammonium hydroxide and which has a number average molecular weight in the range between about 500 and 400, thereby providing a stain-resistant substrate suitable for immediate use in carpeting, upholstery, or the like.
- 9. The substrate of claim 8 wherein said amoutn is between 0.1 2% by weight and said ethylenically unsaturated aromatic monomer can be represented by the formula ##STR9## wherein R is ##STR10## R.sup.1 H--, CH.sub.3 ; or ##STR11## R.sup.2 is H--or CH.sub.3 --; R.sup.3 is H--or CH.sub.3 O--;
- R.sup.4 is H--, CH.sub.3 --; or ##STR12## R.sup.3 plus R.sup.4 is --O--CH.sub.2 --O--.
- 10. The process of claim 8 wherein said ethylenically unsaturated aromatic monomer is styrene.
- 11. The process of claim 8 wherein said polymer contains about one polymer unit derived from maleic anhydride per polymer unit derived from one or more ethylenically unsaturated aromatic monomers.
- 12. The process of claim 8 wherein said polymer contains about one polymer unit derived from maleic anhydride per polymer derived from styrene.
- 13. The process of claim 8 wherein said polymer is hydrolyzed in the presence of sodium hydroxide.
- 14. The process of claim 13 wherein said polymer contains about one polymer unit derived from maleic anhydride per polymer unit derived from styrene.
