Description

POLYMER CONTAINING CONFIGURATION OF OXIDIZED GALACTOSE-TYPE ALCOHOL IN COMBINATION WITH CATIONIC POLYMERS FOR APPLICATIONS OF PAPER STRENGTH Background of the Invention 1. Field of the Invention The present invention relates to a new process for improving paper strength and more particularly relates to the use in combinations of cationic polymers and galactose oxidase-containing polymer in the paper production process. 2 • Description of the Prior Art The product of the oxidation of aqueous solutions of guar gum and other polysaccharides containing galactose using enzyme galactose oxidase was described by F.J. Germino in the US patent. No. 3,297,604. The oxidized products containing aldehyde are separated by precipitation from aqueous solutions used for the enzyme reactions. Germino described the use of rusted products in papermaking. Oxidized products containing aldehyde were also described as suitable for use in the crosslinking of polyamino polymers, polyhydroxy polymers and proteins.
C. Chiu et al., In the patent of the U.S.A. No. 5,554,745, describe (1) the preparation of polysaccharides containing cationic galactose and (2) the enzymatic oxidation in aqueous solution of the polysaccharides containing cationic galactose with galactose oxidase. It is disclosed that oxidized cationic polysaccharides improve the strength characteristics of paper. SUMMARY OF THE INVENTION According to the present invention, there is provided a process for producing paper having improved strength characteristics by providing pulp and adding (1) cationic polymer and (2) polymer containing oxidized galactose-like alcohol configuration wherein the alcohol it has been oxidized in aldehyde, and form sheets and dry the paper, provided that when the polymer containing oxidized galactose-type alcohol configuration is oxidized guar it is selected from the group consisting of oxidized neutral guar, oxidized anionic guar and amphoteric guar oxidized amphoteric amp. In addition, according to the present invention, paper products having improved strength characteristics are provided which are prepared by using the combination of cationic polymers and polymers containing oxidized galactose-type alcohol configuration.
DETAILED DESCRIPTION OF THE INVENTION It has surprisingly been found that polymers containing oxidized galactose-type alcohol configuration such as oxidized anionic and / or amphoteric neutral guar, in combination with water-soluble or water-dispersible cationic polymers, give sufficiently improved resistance to guars not oxidized or oxidized alone. The polymer treatment containing oxidized galactose-type alcohol configuration with galactose oxidase and catalase is the subject of the accompanying patent application Serial No. 09 / 001,789, filed on December 31, 1997 (Hercules file No. PCH 5484, "Oxidation in Solid State of Oxidizable Galactose Type of Alcohol Configuration Containing Polymers "(Oxidation in solid state of polymers containing oxidized galactose type alcohol configuration) by RL Brady, R T. Leibfried and TT Nguyen), the description of which is incorporated herein by reference. The oxidizable galactose alcohol type configuration can be described by the following chemical structures: R3 wherein: R1 = is an alkyl group of the formula C (n) H (2n + 1) where n = 0-20: z = 0.1; R2 = is a linking group which is composed of an alkylene or an aromatic alkylene or an alkylene ether, or an alkylene ester or an alkylene amide, or a diradical alkylene urethane. These linking groups have a total number of carbon atoms from 2 to 20: R3 = -H, -OH, -0CH3, -OC2H5, -OC3H7, -OC4H9, -OOCRs (where R5 = alkyl radical with 1 to 5 carbon atoms), -NH2, -NH-CO-R5; e y = O, 1. Polymers containing oxidized galactose-type alcohol configuration can be galactomannan gums or their ether derivatives, arabinogalactan gums or their ether derivatives, other gums or their ether derivatives, hemicelluloses galactoglucomannan or its ether derivatives and polymers modified enzymatically or synthetically. Preferred galactomannan gums are guar, carob, tara and fenugreek. Preferred arabinogalactan gums are gum arabic, larch and tragacanth. Enzymatically or synthetically preferred modified polymers are polysaccharides deficient in galactose, polyacrylamides, polyacrylates, polyamides, polyvinyl alcohol and polyvinyl acetate. Particular preference is given to these polymers, starch and polyacrylates. The phrase "galactose-deficient" as used in the present application means that the polymer containing oxidized galactose-type alcohol configuration to which it refers contains less than 20% oxidizable galactose-type alcohol configuration based on the weight of the polymer that contains oxidized galactose type alcohol configuration. Other preferred gums are carbine, lichen, tamarind and potato galactane. More preferred oxidized galactose-type alcohol-containing polymers are guar gum and its ether derivatives such as hydroxypropyl, dihydroxypropyl and hydroxyethyl guar anionic, amphoteric. Synthetically or enzymatically modified polymers can be obtained by transferring an oxidizable galactose-type alcohol configuration into polymers. Glycocyl transferases or hydrolases can be used to transfer galactose from lactose for example polyaccarides to provide polymers useful for oxidation. Synthetic methods can also be obtained to connect the oxidizable galactose alcohol type configuration. By these methods, other saccharides such as gulose, fructose, sorbose, mannose, talose, gilose and ribose can be connected to polymers by providing candidates for oxidation. The polymer component containing oxidized galactose-type alcohol configuration of the present invention has at least about 5 mol% of its oxidizable, galactose-type alcohol configuration, oxidized in aldehyde. Preferably, at least about 25 mol% and more preferably at least 50 mol% of this alcohol has been oxidized in aldehyde. The polymer containing oxidized galactose-type alcohol configuration used for oxidation may be in the range over a wide molecular weight range. It can be a high molecular weight, or alternatively it can be a depolymerized polymer (of reduced viscosity). In general, the lower limit of the weight average molecular weight of the polymer containing oxidized galactose-type alcohol configuration may be about 5,000. The upper limit of the polymer containing oxidized galactose-type alcohol configuration may be about 5,000,000. Preferably, the molecular weight range as indicated by the Brookfield viscosity at room temperature is at least about 15 cps to 2 weight percent in solution in water, more preferably at least about 100 cps to 1 weight percent in solution in water. Preferably, the Brookfield viscosity at room temperature can be up to about 10,000 cps, and more preferably up to about 6,000 cps to 1 weight percent in solution in water, (measured in the Brookfield LVT viscometer with a small sample adapter, ° C, spindle 31, speed 3 rpm). Oxidized guar is preferred as the polymer containing oxidized galactose-type alcohol configuration for use in the present invention. The present application relates to guar oxidized specifically in certain cases, however the person of ordinary skill in the art will recognize that these teachings apply to the polymer containing oxidized galactose-like alcohol configuration in general. The polymer containing oxidized galactose-type alcohol configuration can be oxidized in solid form, in the form of sludge or in solution. The oxidation can be carried out chemically or enzymatically by galactose oxidase. Neutral or anionic or amphoteric guar that has been oxidized by galactose oxidase and catalase is used in the present invention. Galactose oxidase can be applied to solid forms, of mud or in solution of guar products: for example shredded, pulverulent, in flakes and nodules, of neutral, anionic or amphoteric guar. Guar derivatives, such as those containing hydroxypropyl groups can also be employed. Galactose oxidase (EC 1.1.3.9) is a copper oxidase that converts the oxidizable galactose-type alcohol configuration into the corresponding aldehyde group (thus producing oxidized galactose) by reducing oxygen in hydrogen peroxide. The copper must be in the correct oxidation state (Cu2 +) to perform this oxidation and the copper ion must be retained in the galactose oxidase. If the galactose oxidase solution is stored anaerobically with any oxidizable substrate, it may become inactive. Galactose oxidase can be reactivated by oxidizing copper with reagents such as potassium ferricyanide. Another way to oxidize copper in galactose oxidase would be by electrochemical oxidation. Galactose oxidase can be obtained by any convenient form, for example by fermenting various wild type and cloned fungi, but usually obtained from Fusarium spp (NRRL 2903). You can also obtain cultures from the American Type Culture Collection (American Type Culture Collection) under Dactilium dendroides ATCC 46032 and successfully fermented under the Tressel and Kosman procedure. Methods in Enzymology (Methods in Enzymology), Vol. 89 (1982), p. 163-172.
The gene for the active forms of the enzyme has been expressed in E. coli and Aspergillus and this development can lead to more stable and active forms of the enzyme, as well as much higher production levels. The gene or improved forms will also be expressed in plants that can be harvested to give higher levels of enzyme, without the threat of destruction of enzyme by proteases in a fermentation broth. The enzyme can also be expressed by other organisms including: Gibberella fujikoroi, Fusarium graminearum and Bettraniella porticensis. The oxidation of galactose oxidase is often carried out in the presence of catalase. The amount of catalase may be at least about one unit of catalase / galactose oxidase unit. Catalase may be present in an amount of up to about 10,000 catalase units / galactose oxidase unit. Catalase destroys the hydrogen peroxide formed from the galactose oxidase reaction. Increased levels of oxidation and corresponding increase in paper strength characteristics is the subject of the accompanying patent application No. 09 / 001,785, filed on December 31, 1997 (Hercules file No. PCH 5522"Use of Oxidation Promoting Chemicals in Enzymatic Oxidation of Galactose Containing Polymers "(Use of oxidation promoting chemicals in enzymatic oxidation of polymers containing galactose) by RL Brady and RT Leibfried), the description of which is incorporated herein by reference. Preferably, the oxidation promoter chemical is organic carboxylate compound, organic heterocyclic compound, chlorinated organic compound and / or quaternary amine compound. More preferably, the organic carboxylate compound is sorbic acid, benzoic acid, toluic acid, phthalic acid, and their corresponding salts, the organic heterocyclic compound, i.e., 1,2-benzisothiazolin-3-one, and / or 2-methyl-4 -isothiazoline-3-one, the chlorinated organic compound is 5-chloro-2-methyl-4-isothiazolin-3 -one, and the quaternary amine compound is cetyltrimethylammonium bromide and / or quaternary epoxy amines. Cationic polymers suitable for use in combination with the polymer containing oxidized galactose-type alcohol configuration in the present invention are cationic water-dispersible and / or water-soluble polymers. The phrase "water-soluble" as used in the present application means a polymer of which at least about 5% by weight is dissolved in water at room temperature. The phrase "water dispersible" as used in the present application means a polymer that can be evenly distributed in water and if it sediments it can be easily redispersed. By cationic is meant anything with a net positive charge at the paper production pH (e.g. pH from about 3 to about 10). This includes amphoteric polymers containing both anionic and cationic sites, these polymers have a net cationic charge. Preferably the cationic polymer is polymeric amine-epichlorohydrin resin, such as polyamide-epichlorohydrin resin (PAE), polyalkylene polyamine-epichlorohydrin resin (PAPAE) and amine-epichlorohydrin polymer resin (APE), in which the amine groups have been alkylated with epichlorohydrin to produce a polyamine-epichlorohydrin resin having azetidinium or epoxide functionality; cationic derivative of polysaccharides (such as starch, guar, cellulose, and chitin; polyamine; polyethyleneimine; vinylalcohol-vinylamine copolymers; acrylic cationic homo- and co-polymers, such as polyacrylamide, polydiallyldimethylammonium chloride, and acrylic acid copolymers, acrylic esters and acrylamide with diallyldimethylammonium chloride, acryloyloxyethyltrimethylammonium chloride, methylaceulfate, ammonium tertiary ammonium, methacryloyloxyethyl trimethylammonium chloride and methacrylamidopropyltrimethylammonium chloride. Cationic polymers are described in more detail in U.S. Pat. No. 5,319,669 and the US patent. No. 5,338,406, the descriptions of which are hereby incorporated by reference. More preferably, the cationic polymer is cationic starch, cationic guar, polyamidoamine-epichlorohydrin resin and / or polyacrylamide. The effectiveness of cationic polymers is particularly evident when used with oxidized anionic guar. The total weight of the polymer containing oxidized galactose-type alcohol (oxidized polymer) plus cationic polymeric configuration is generally at least about 0.05%, preferably at least about 0.1%, and most preferably at least about 0.15% based on weight Dry the paper. The total weight of the oxidized polymer plus cationic polymer is generally up to about 5%, preferably up to about 1% and in particular to about 0.5% based on the dry weight of the paper. The weight ratio of oxidized polymer to cationic polymer in general can be at least about 1:20, preferably at least about 1: 4 and in particular at least about 1: 1. The weight ratio of oxidized polymer to cationic polymer in general can be up to about 100: 1, preferably up to about 50: 1 and in particular up to about 20: 1. The optimum ratio of oxidized polymer to cationic polymer will depend on the oxidized polymer employed, the cationic polymer employed and the type of raw materials (ie, pulp, pH, fillers, etc.) employed. The components of this invention - the cationic polymer and the polymer containing oxidized galactose-type alcohol configuration - can be added at any point in the paper production process, that is, either before or after sheeting. For example, they can be added before the sheeting (1) early during the preparation of the pulp in the sludge container or refining container (2) in the machine container or container of material, (3) at other points in the the wet end such as the fan pump or in-line mixers. It can also be added to the white water container. Examples of addition after sheeting are in the sizing press or even as a subsequent coating process. The components can be premixed or added separately in any order. The preferred practice in the wet state, however, is to add the cationic polymer first.
