MALEIC ANHYDRIDE/OLEFIN POLYMER STAIN-RESISTS
FIELD OF THE INVENTION
The present invention relates to polyamide textile substrates treated with stain-resistant compositions comprising water-soluble or water-dispersible maleic anhydride/ alpha-olefin polymers, and processes for their synthesis. The substrates of this invention possess stain-resistance but do not suffer from yellowing to the extent that some previously known materials do.
BACKGROUND OF THE INVENTION
Polyamide substrates, such as nylon carpeting, upholstery fabric and the like, are subject to staining by a variety of agents, e.g., foods and beverages. An especially troublesome staining agent is FD&C Red Dye No. 40, commonly found in soft drink preparations.
Different types of treatments have been proposed to deal with staining problems. One approach is to apply a highly fluorinated polymer to the substrate. Another is to use a composition containing a sulfonated phenol-formaldehyde condensation product.
For example, Liss et al., in U.S. Patent No.
4,963,409, disclose stain-resistant synthetic polyamide textile substrates having deposited on them sulfonated phenol-formaldehyde polymeric condensation products.
However, sulfonated phenol-formaldehyde condenation products are themselves subject to discoloration;
commonly they turn yellow. Yellowing problems are described by W. H. Hemmpel in a March 19, 1982 article in America's Textiles, entitled Reversible Yellowing Not Finisher's Fault. Hemmpel attributes yellowing to exposure of a phenol-based finish to nitrogen oxides `.

and/or ultraviolet radiation. To deal with the yellowing problem, the condensation products were modified by Liss et al. by acylation or etherification of some of the phenolic hydroxyls. In a preferred embodiment disclosed by Liss et al., the modified condensation products were dissolved in a hydroxy-containing solvent, such as ethylene glycol prior to there being applied to the textile substrate.
Allen et al., in U.S. Patent 3,83S,071, disclose rug shampoo compositions which upon drying leave very brittle, non-tacky residues which are easily removed when dry. The compositions comprise water-soluble metal, ammonium or amine salt of a styrene-maleic anhydride copolymer, or its half ester, and a detergent. Water-soluble metal salts of Group II and the alkali metals (particularly magnesium and sodium) are preferred and ammonium salts are most preferred by Allen et al.
On the other hand, Fitzgerald et al., in U.S. Patent Application Serial No. 07/502819, filed 2 April 1990, disclose the usefulness of agueous solutions of hydrolyzed vinylaromatic/maleic anhydride copolymers in the treatment of textiles to render them resistant to staining. The preferred copolymer of Fitzgerald et al. is a hydrolyzed styrene/maleic anhydride copolymer. Fitz~erald et al. disclose that - the monoalkyl ester of their maleic anhydride/vinyl aromatic polymer was ineffective as a stain-resist.
Maleic anhydride/alpha-olefin polymers are known. U.S. Reissue Patent No. 28,475 discloses copolymerization of maleic anhydride and l-olefins, such as, l-hexene, l-tetradecene and l-octadecene.

BRIEF SUMMARY OF THE INVENTION
The present invention provides polyamide fibrous substrates treated with water-soluble or water-dispersible maleic anhydride/alpha-olefin polymers so as to impart stain-resistance to the substrates, and methods for preparing the same.
Commonly, prior art materials known to be useful as stain-blockers were sulfonated phenol-formaldehyde condensates (excepting those of Fitzgerald et al., supra). Finding a non-sulfonated material, such as the water-soluble or water-dispersible alpha-olefin/maleic anhydride polymers of this invention, to be useful for this purpose was unexpected.
DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to the use of water-soluble or water-dispersible maleic anhydride/alpha-olefin polymers, or mixtures of the same, as stain-resists for fibrous polyamides. A
variety of linear and branched chain alpha-olefins can be used for the purposes of this invention.
Particularly useful alpha-olefins are dienes containing 4 to 18 carbon atoms, such as butadiene, chloroprene, isoprene, and 2-methyl-l,5-hexadiene; l-alkenes containing 4 to 8 carbon atoms, preferably C4_l0, such as isobutylene, l-butene, l-hexene, l-octene, and the like, with isobutylene being most preferred. A part of the alpha-olefins can be replaced by other monomers, : .

e.g. up to 50 wt% of alkyl(Cl_4) acrylates, alkyl(Cl_4) methacrylates, vinyl acetate, vinyl chloride, vinylidine chloride, vinyl sulfides, N-vinyl pyrrolidone, acrylonitrile, acrylamide, as well as mixtures of the same.
A part (1-75%) of the maleic anhydride can be replaced by maleimide, N-alkyl(Cl_4) maleimides, N-phenyl-maleimide, fumaric acid, itaconic acid, citraconic acid, aconitic acid, crotonic acid, cinnamic acid, alkyl(Cl_lg) esters of the foregoing acids, cycloalkyl(C3_8) esters of the foregoing acids, sulfated castor oil, or the like.
At least 95 wt% of the maleic anhydride co- or terpolymers have a number average molecular weight of in the range between about 700 and 200,000, preferrably between about lO00 and lO0,000.
In accordance with the present invention, it has been unexpectedly found that water-soluble or water-dispersible interpolymers (i.e. copolymers, terpolymers, and the like) of maleic anhydride and one or more l-alkenes having 4 to 8 carbon atoms, particularly isobutylene, l-hexene and l-octene, impart excellent stain-resistance to polyamide substrates (e.g. carpeting) at low pH. Copolymers of maleic anhydride with butadiene or propylene were found by the inventor to be less effective as stain-resists on such substrates than were interpolymers of maleic anhydride and l-alkenes containing 4 to 8 carbon atoms.
Surprisingly, he found also that copolymers of maleic anhydride and at least one olefin selected from ethyleen and l-alkenes having lO to 24 carbon atoms impart no detectable stain-resistance to such substrates.
The maleic anhydride polymers useful in the present invention can be prepared according to methods . . .: , , , 2~S(~12~' WO92/10605 PCT/US91/091~5 well-known in the art. The maleic anhydride polymers thus obtained can be hydrolyzed to the free acid or their salts by reaction with water or alkali, or they can also be reacted with Cl_4 alkyl alcohol to provide polymeric alpha-olefin/maleic acid monoesters, which have stainblocking properties. Generally, the hydrolyzed maleic anhydride polymer, or the monoester polymer, should be sufficiently water-soluble that uniform application to a fibrous polyamide surface can be achieved at an appropriate acidity. However, applications using water dispersions of the polymer mixed with a suitable surfactant may be used to impart stain-resistance.
one can blend the stain-resists of the present invention with other known stain-resists, such as phenol-formaldehyde condensation products as disclosed in U.S. Patents 4,833,009 and 4,965,325; methacrylic acid polymers disclosed in U.S. Patent No. 4,937,123;
or hydrolized polymers of maleic anhydride and one or more ethylenically unsaturated aromatic compounds described by Fitzgerald et al., supra.
The polymers suitable for the purposes of this invention contain between about 0.7 and 1.3 polymer units derived from one or more alpha-olefin monomers per polymer unit derived from maleic anhydride. The alpha-olefin content of the polymers of this invention comprise between (a) 100 and 80 mol% of at least one 1-alkene containing 4 to 8 carbon atoms or terminally unsaturated diene containing 4 to 18 carbon atoms and (b) 0 to 20 mol% of at least one 1-alkene containing 3, or 10 to 18, carbon atoms. Polymers containing about one polymer unit derived from one or more olefin monomers per polymer unit derived from maleic anhydride are most effective in imparting stain resistance to textile substrates. The molecular weight of the WO92/10605 2 ~ ~ ù 12 ~ PCT/US91/09155 polymers useful in the invention does not appear to be a limitation so long as the polymers are water-soluble or water-dispersible. Thus, for example, hydrolyzed isobutylene/maleic anhydride copolymers having number average molecular weights between about 6000 and lOo,oO0 impart good stain-resistance to polyamide substrates. Even at a pH as low as l.5, water-soluble isobutylene/maleic anhydride copolymers having number average molecular weights between about 6000 and lO0,000 remained in solution in water at 60OC.
The polymers suitable for the purposes of this invention can be prepared by hydrolyzing the maleic anhydridetolefin polymers according to methods well-known in the art. For example, they can be lS hydrolyzed to the free acid or their salts by reaction with water or alkali. Generally, the maleic anhydride polymer should be sufficiently water-soluble that uniform application to a fiber surface can be achieved at an appropiate acidity. ~owever, applications using dispersions of the polymers with suitable surfactants may be used to impart stain-resistance.
The olefin/maleic anhydride polymers of this invention can be used as such in treating polyamide textile substrates. They can be effectively applied to polyamide fibrous substrates by a wide variety of methods known to those skilled in the art, such as:
padding, spraying, foaming in conjunction with foaming agents, batch exhaust in beck dyeing equipment, or continuous exhaust during a continuous dyeing operation.
They can be applied by such methods to dyed or undyed polyamide textile substrates. In addition, they can be -.

~ ~W092/1 ~ 5 2 0 9 ~ ~ 2 ~ PCT/US91/09155 applied to such substrates in the absence or presence of a polyfluoroorganic oil-, water-, and/or soil-repellent materials. In the alternative, such a polyfluoroorganic material can be applied to the textile substrate before or after application of the polymers of this invention thereto.
The quantities of the polymers of this invention which are applied to the textile substrate are amounts ef~ective in imparting stain-resistance to the substrate. Those amounts can be varied widely; in general, one can use between l and 5% by weight of them based on the weight of the textile substrate, usually 2.5% by weight or less. The polymers can be applied, as is common in the art, at pHs ranging between about 2 lS and 7. However, more effective exhaust deposition can be obtained at a pH as low as l.5. When the latter low pH is used, the preferred level of application to the textile substrate is about 2.5% by weight, based on the weight of the textile substrate. In an embodiment, a pH between about 2 and 3 is used. Nore effective stainblocking is obtained if the polymers are applied to the textile substrate at either 20C
followed by heat treatment at a temperature in the range between about 50 and 150C for about l to 60 minutes, or applied at temperatures in the range between about 40 and 95C for about l to 60 minutes.
For example, at a pH between about 2 and 3, a temperature between about 70 and 90C is preferred.
However, stain-blocking can be obtained when application is effected even at that of cold tap water (10-15C).
The polymers of this invention can also be applied in-place to polyamide carpeting which has already been installed in a dwelling place, office or other locale. They can be applied as a simple aqueous `:

preparation or in the form of aqueous shampoo preparation, with or without one or more polyfluoro-organic oil-, water-, and/or soil-repellent materials.
They may be applied at the levels described above, at s temperatures described, and at a pH between about 1 and 12, preferably between about 2 and 9.

MALEIC ANHYDRIDE/OLEFIN POLYMER STAIN-RESISTS
FIELD OF THE INVENTION
The present invention relates to polyamide textile substrates treated with stain-resistant compositions comprising water-soluble or water-dispersible maleic anhydride/ alpha-olefin polymers, and processes for their synthesis. The substrates of this invention possess stain-resistance but do not suffer from yellowing to the extent that some previously known materials do.
BACKGROUND OF THE INVENTION
Polyamide substrates, such as nylon carpeting, upholstery fabric and the like, are subject to staining by a variety of agents, e.g., foods and beverages. An especially troublesome staining agent is FD&C Red Dye No. 40, commonly found in soft drink preparations.
Different types of treatments have been proposed to deal with staining problems. One approach is to apply a highly fluorinated polymer to the substrate. Another is to use a composition containing a sulfonated phenol-formaldehyde condensation product.
For example, Liss et al., in U.S. Patent No.
4,963,409, disclose stain-resistant synthetic polyamide textile substrates having deposited on them sulfonated phenol-formaldehyde polymeric condensation products.
However, sulfonated phenol-formaldehyde condenation products are themselves subject to discoloration;
commonly they turn yellow. Yellowing problems are described by W. H. Hemmpel in a March 19, 1982 article in America's Textiles, entitled Reversible Yellowing Not Finisher's Fault. Hemmpel attributes yellowing to exposure of a phenol-based finish to nitrogen oxides `.

and/or ultraviolet radiation. To deal with the yellowing problem, the condensation products were modified by Liss et al. by acylation or etherification of some of the phenolic hydroxyls. In a preferred embodiment disclosed by Liss et al., the modified condensation products were dissolved in a hydroxy-containing solvent, such as ethylene glycol prior to there being applied to the textile substrate.
Allen et al., in U.S. Patent 3,83S,071, disclose rug shampoo compositions which upon drying leave very brittle, non-tacky residues which are easily removed when dry. The compositions comprise water-soluble metal, ammonium or amine salt of a styrene-maleic anhydride copolymer, or its half ester, and a detergent. Water-soluble metal salts of Group II and the alkali metals (particularly magnesium and sodium) are preferred and ammonium salts are most preferred by Allen et al.
On the other hand, Fitzgerald et al., in U.S. Patent Application Serial No. 07/502819, filed 2 April 1990, disclose the usefulness of agueous solutions of hydrolyzed vinylaromatic/maleic anhydride copolymers in the treatment of textiles to render them resistant to staining. The preferred copolymer of Fitzgerald et al. is a hydrolyzed styrene/maleic anhydride copolymer. Fitz~erald et al. disclose that - the monoalkyl ester of their maleic anhydride/vinyl aromatic polymer was ineffective as a stain-resist.
Maleic anhydride/alpha-olefin polymers are known. U.S. Reissue Patent No. 28,475 discloses copolymerization of maleic anhydride and l-olefins, such as, l-hexene, l-tetradecene and l-octadecene.

BRIEF SUMMARY OF THE INVENTION
The present invention provides polyamide fibrous substrates treated with water-soluble or water-dispersible maleic anhydride/alpha-olefin polymers so as to impart stain-resistance to the substrates, and methods for preparing the same.
Commonly, prior art materials known to be useful as stain-blockers were sulfonated phenol-formaldehyde condensates (excepting those of Fitzgerald et al., supra). Finding a non-sulfonated material, such as the water-soluble or water-dispersible alpha-olefin/maleic anhydride polymers of this invention, to be useful for this purpose was unexpected.
DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to the use of water-soluble or water-dispersible maleic anhydride/alpha-olefin polymers, or mixtures of the same, as stain-resists for fibrous polyamides. A
variety of linear and branched chain alpha-olefins can be used for the purposes of this invention.
Particularly useful alpha-olefins are dienes containing 4 to 18 carbon atoms, such as butadiene, chloroprene, isoprene, and 2-methyl-l,5-hexadiene; l-alkenes containing 4 to 8 carbon atoms, preferably C4_l0, such as isobutylene, l-butene, l-hexene, l-octene, and the like, with isobutylene being most preferred. A part of the alpha-olefins can be replaced by other monomers, : .

e.g. up to 50 wt% of alkyl(Cl_4) acrylates, alkyl(Cl_4) methacrylates, vinyl acetate, vinyl chloride, vinylidine chloride, vinyl sulfides, N-vinyl pyrrolidone, acrylonitrile, acrylamide, as well as mixtures of the same.
A part (1-75%) of the maleic anhydride can be replaced by maleimide, N-alkyl(Cl_4) maleimides, N-phenyl-maleimide, fumaric acid, itaconic acid, citraconic acid, aconitic acid, crotonic acid, cinnamic acid, alkyl(Cl_lg) esters of the foregoing acids, cycloalkyl(C3_8) esters of the foregoing acids, sulfated castor oil, or the like.
At least 95 wt% of the maleic anhydride co- or terpolymers have a number average molecular weight of in the range between about 700 and 200,000, preferrably between about lO00 and lO0,000.
In accordance with the present invention, it has been unexpectedly found that water-soluble or water-dispersible interpolymers (i.e. copolymers, terpolymers, and the like) of maleic anhydride and one or more l-alkenes having 4 to 8 carbon atoms, particularly isobutylene, l-hexene and l-octene, impart excellent stain-resistance to polyamide substrates (e.g. carpeting) at low pH. Copolymers of maleic anhydride with butadiene or propylene were found by the inventor to be less effective as stain-resists on such substrates than were interpolymers of maleic anhydride and l-alkenes containing 4 to 8 carbon atoms.
Surprisingly, he found also that copolymers of maleic anhydride and at least one olefin selected from ethyleen and l-alkenes having lO to 24 carbon atoms impart no detectable stain-resistance to such substrates.
The maleic anhydride polymers useful in the present invention can be prepared according to methods . . .: , , , 2~S(~12~' WO92/10605 PCT/US91/091~5 well-known in the art. The maleic anhydride polymers thus obtained can be hydrolyzed to the free acid or their salts by reaction with water or alkali, or they can also be reacted with Cl_4 alkyl alcohol to provide polymeric alpha-olefin/maleic acid monoesters, which have stainblocking properties. Generally, the hydrolyzed maleic anhydride polymer, or the monoester polymer, should be sufficiently water-soluble that uniform application to a fibrous polyamide surface can be achieved at an appropriate acidity. However, applications using water dispersions of the polymer mixed with a suitable surfactant may be used to impart stain-resistance.
one can blend the stain-resists of the present invention with other known stain-resists, such as phenol-formaldehyde condensation products as disclosed in U.S. Patents 4,833,009 and 4,965,325; methacrylic acid polymers disclosed in U.S. Patent No. 4,937,123;
or hydrolized polymers of maleic anhydride and one or more ethylenically unsaturated aromatic compounds described by Fitzgerald et al., supra.
The polymers suitable for the purposes of this invention contain between about 0.7 and 1.3 polymer units derived from one or more alpha-olefin monomers per polymer unit derived from maleic anhydride. The alpha-olefin content of the polymers of this invention comprise between (a) 100 and 80 mol% of at least one 1-alkene containing 4 to 8 carbon atoms or terminally unsaturated diene containing 4 to 18 carbon atoms and (b) 0 to 20 mol% of at least one 1-alkene containing 3, or 10 to 18, carbon atoms. Polymers containing about one polymer unit derived from one or more olefin monomers per polymer unit derived from maleic anhydride are most effective in imparting stain resistance to textile substrates. The molecular weight of the WO92/10605 2 ~ ~ ù 12 ~ PCT/US91/09155 polymers useful in the invention does not appear to be a limitation so long as the polymers are water-soluble or water-dispersible. Thus, for example, hydrolyzed isobutylene/maleic anhydride copolymers having number average molecular weights between about 6000 and lOo,oO0 impart good stain-resistance to polyamide substrates. Even at a pH as low as l.5, water-soluble isobutylene/maleic anhydride copolymers having number average molecular weights between about 6000 and lO0,000 remained in solution in water at 60OC.
The polymers suitable for the purposes of this invention can be prepared by hydrolyzing the maleic anhydridetolefin polymers according to methods well-known in the art. For example, they can be lS hydrolyzed to the free acid or their salts by reaction with water or alkali. Generally, the maleic anhydride polymer should be sufficiently water-soluble that uniform application to a fiber surface can be achieved at an appropiate acidity. ~owever, applications using dispersions of the polymers with suitable surfactants may be used to impart stain-resistance.
The olefin/maleic anhydride polymers of this invention can be used as such in treating polyamide textile substrates. They can be effectively applied to polyamide fibrous substrates by a wide variety of methods known to those skilled in the art, such as:
padding, spraying, foaming in conjunction with foaming agents, batch exhaust in beck dyeing equipment, or continuous exhaust during a continuous dyeing operation.
They can be applied by such methods to dyed or undyed polyamide textile substrates. In addition, they can be -.
, .
~ ~W092/1 ~ 5 2 0 9 ~ ~ 2 ~ PCT/US91/09155 applied to such substrates in the absence or presence of a polyfluoroorganic oil-, water-, and/or soil-repellent materials. In the alternative, such a polyfluoroorganic material can be applied to the textile substrate before or after application of the polymers of this invention thereto.
The quantities of the polymers of this invention which are applied to the textile substrate are amounts ef~ective in imparting stain-resistance to the substrate. Those amounts can be varied widely; in general, one can use between l and 5% by weight of them based on the weight of the textile substrate, usually 2.5% by weight or less. The polymers can be applied, as is common in the art, at pHs ranging between about 2 lS and 7. However, more effective exhaust deposition can be obtained at a pH as low as l.5. When the latter low pH is used, the preferred level of application to the textile substrate is about 2.5% by weight, based on the weight of the textile substrate. In an embodiment, a pH between about 2 and 3 is used. Nore effective stainblocking is obtained if the polymers are applied to the textile substrate at either 20C
followed by heat treatment at a temperature in the range between about 50 and 150C for about l to 60 minutes, or applied at temperatures in the range between about 40 and 95C for about l to 60 minutes.
For example, at a pH between about 2 and 3, a temperature between about 70 and 90C is preferred.
However, stain-blocking can be obtained when application is effected even at that of cold tap water (10-15C).
The polymers of this invention can also be applied in-place to polyamide carpeting which has already been installed in a dwelling place, office or other locale. They can be applied as a simple aqueous `:

preparation or in the form of aqueous shampoo preparation, with or without one or more polyfluoro-organic oil-, water-, and/or soil-repellent materials.
They may be applied at the levels described above, at s temperatures described, and at a pH between about 1 and 12, preferably between about 2 and 9.
