The resulting polymers can be used in the pulp and paper industry to improve dewatering, retain scraps of fibers, dyes, pigments, fillers, starch, resin, and increase strength. In addition, these polymers can be used as resins for the manufacture of conductive paper and paper and cardboard sizing, as well as in ore processing operations for the separation of minerals.

They are also effective for algae, bacterium and d) ibc control in swimming pools and in industrial water treatment and cooling processes.

A known method for producing a polymer electrolyte by the polycondensation of ammonia or primary amines, followed by curing of the condensation product with di- and polyamines (for example, anioite AH-31) l.

However, the field of application of the resulting electrolyte is limited.

The closest to the invention to the technical essence is the method of obtaining a polymer electrolyte, which consists in the post-condensation of ammonia or a primary amine with epichlorohydrin, followed by curing the product of condensation with a tertiary amine having a grouping

for example, diaminoisopropanol or its higher homologues 2.

The polymers produced according to this method are used in the mining industry to separate germanium from satellites.

The aim of the invention is to enhance the functionality of polymer electrolytes, i.e. increasing their spectrum of action. This goal is achieved by the fact that in the method of producing polymer electrolyte by polycondensing ammonia or a primary amine with epichlorohydrin, followed by treating the resulting product with a tertiary amine, for polycondensation, take 1 mole of primary cmin for 2 mol of epichlorohydrin. or 1 mole of ammonia per 3 mole of epichlorohydrin, and the following formulas are used as the tertiary amine; V to -K- 1 1g-CHg-C-andHg / -X-FC where R is a straight or branched aliphatic group containing 1-20 atmus angle or 1-6 carbon atoms and at least one strong hydra or chlorine substituent alicyclic alkaryl or aryl groups; R is a straight aliphatic group containing 1-6 X atoms; a polymethylene group, with 1-12 carbon atoms, -CHH-CH-CHg H CHj-CHf-O-CHz-CHz-k / and -HN- CH CH-C New cationic, water-soluble amino-epichlorohydrin compounds prepared according to the invention have the following structure: GL-H-Hg-BH-CHG-k-eHz-feH-dHt-l: Lej- .eJn where n is an integer; f Г -N-Х-К®iieR ti®R or НО -N - С®bl®R В -Сн2-с1н-СНг-к-Нг-Эен-С.Нг-А Н ®Ь®-СНг-Н -СНг-М- (JHz-tjK-CHz-; ® (1,1®СНз on X - polyethylene group containing 1-12 carbon atoms, -b HgCn-Cng-; - (/ EriHrO-H-2- "lHz - it is -CHg-CH CH-CHg - linear or branched aliphatic group containing 1-20 carbon atoms and U-2 carbon-carbon double bonds, linear or branched aliphatic group containing 1-6 carbon atoms and one or more hydroxyl or chlorine as substituents, an alicyclic group or an alkaryl group. Each of the R-groups is independently alylphatic. linear or branched chain pairs containing 1-20 carbon atoms and 0-2 carbon-carbon tunked bonds, a linear or branched aliphatic group containing 1-6 carbon atoms and one or more hydroxyl substituent, alicyclic group, alkaryl group or an aryl group. T1 is a linear chain aliphatic group containing 1-6 carbon atoms. The polymers of this invention are prepared by a two-step reaction. In the first stage, 1 mol of the primary amine reacts with 2 mol of epichlorohydrin or 1 mol of ammonia reacts with 3 mol of epichlorohydrin to form a prepolymer. The reaction is best carried out in the presence of polar solvents, such as methanol, ethanol, 1-propanol or 2-propanol. Some amount of water may be present, but the amount of water must be less than the amount of organic solvent. During the addition of the first mole of epichlorohydrin to the amine solution the reaction temperature should be below 30 ° C. Even the reaction can be carried out at 60-70 ° C. Primary C1mins other than lower alkylamines require a higher temperature to complete the reaction. The first compound formed in this reaction is a tertiary amine containing at least 2 H-chloro-2-hydroxypropyl substituents. Since compounds of this type contain at least two reactive chlorine atoms and a tertiary nitrogen atom, the ethylamines themselves react with itself, with the formation of branched polymers of quaternary ammonium compounds. This polymerization will take place even at room temperature and is boosted if the reaction mixture is kept warm. To control the reduction of the tertiary amine content, conventional analytical methods can be applied and the corresponding increase in ionic chloride as a compound of the fourth ammonium can be HAPPENED. Tertiary amines, formed from 1 mol of the primary amine and 2 mol of epichlorohydrin or their ammonia and 3 mol of epichlorohydrin, contain at least 2 active chlorine atoms and only 1 nitrogen atom. In the quaternization reaction in the prepolymer, there will still be between half and two thirds of the active chlorine atoms for the further reaction. According to the invention, this prepolymer will react with tertiary amines to form water-soluble polymers. When the prepolymer reacts with compounds containing only one tertiary nitrogen during the second stage, no further polymerization occurs, since the reaction involves the conversion of the chlorine of the terminal group to quaternary nitrogen chloride. The amount of added mono-tert-amine depends on the still existing organic chlorine. When di-tert-amine reacts with the prepolymer, two or more molecules of the prepolymer will join together when both atoms of the di-tert-amine are quaternized. Branching or draining can be controlled by varying the amount of di-tert-amine added. If the stoichiometric ratio of tertiary nitrogen atoms to the prepolymer monomer is 1 or more than 1, then less branching or crosslinking occurs. High molecular weight polymers are obtained when the molar ratio of di-tert-amine to bis {3-chloro-2-hydroxypropyl) amine, based on the monomer, is less than 0.95: 1. When equimolecular ratios are used, polymers of lower molecular weight are obtained. However, adding prepolymer to these polymers of lower molecular weight to provide a low molar excess of prepolymer will increase the molecular weight of the final product. The tertiary amines prepolymer reaction is carried out at 60-100 ° C in an aqueous solution. The alcohol solvent used in the prepolymer reaction may be left in the reaction mixture, but the best products are obtained by removing the solvent by distillation as the reaction proceeds. When di-tert-amines react with the prepolymer as described, the desired molecular weight will be obtained while unreacted tert-amine groups are still present. Thus, the reaction will continue even at room temperature for several days. The polymer composition can be left on the desired molecular weight by adding mineral acids to form a salt with unreacted thr. Amine. The reaction of the prepolymer with di-tert-amine is facilitated if the reactants are maintained at a high concentration. As the polymerization progresses and viscosity increases, water is added, while heating continues until the desired viscosity and concentration is reached. The reaction is stopped by adding a sufficient amount of mineral acid; 7 converting the whole unreacted tert-amine to the salt. For a clearer understanding of the nature of the invention, the following is a list of specific primary amines, tertiary amines, containing one tertiary nitrogen and tertiary amines, containing two tertiary nitrogen atoms, suitable for use in the invention. However, the list is given only for the purpose of illustration and the invention is not limited to the use of these specific amines. Primary amines found satisfactory for reaction with epichlorohydrin to form a prepolymer include aliphatic, alicyclic, and alkylaromatic amines, which may be substituted by hydroxyl groups or chlorine, or may contain double carbon bonds. Aliphatic groups in these amines can be straight-chained or branched. Examples of these amines are the following: Methylamine tert-Octylamine Ethylamine Stearylamine n-Propylamine Cyclohexylamine Z-chloro-2-hydroxy-Hexylamine propylamine Isopropylamine Benzylamine tris (Hydroxymethyl) methylamine n-Butylamine ethanolam-3-Hydroxy-3-Hydroxy-3 Isopropanolamine. Tertiary amines containing one tertiary nitrogen atom that may react with the prepolymer include aliphatic, aromatic, and heterocyclic amines. Aliphatic groups may contain one or more carbon double bonds and may be substituted with hydroxyl groups. Examples of these aminovs are:

Didecylmethyl Trimethylamine

Dimethyl myristyl Triethylamine

amine

N, N-Dimethylanydimethylstearylamine LINE

Dimethyldecylamine Pyridine

N, N-dimethylbeneyl amine

Triethanolamine

N, N-dimethylethanolamine

Tertiary amines containing two tertiary nitrogen atoms that can react with the prepolymer include the following amines:

N, N, N, N - Tetramethyl-1,2-diaminoethane

N, N, N, N -Tetramethyl-1,3-diaminopropane

N, N, N, N - Tetramethyldiaminobutane N, N, N, N - Tetramethyl-1, 4-diaminobutane

N, N, N; N.- Tetramethyl-1,6-diaminohexane

N, N, N, N - Tetramethyl-1,3-diamino-2-propanol

N, N, N, N - Tetramethyl-1,4-diaminobutene-2

N, N, N, N - Tetramethylmethylenediamine bis (beta-dimethylaminoethyl) ether.

Suitable solvents that may be used in preparing the prepolymer include methanol, ethanol, 1-propanol, 2-g 1-propanol, and other polar solvents, including mixtures with water. If it is desirable to isolate the prepolymer, solvents such as hexane, benzene, toluene, or xylene may be used. The prepolymer is precipitated and can be removed by filtration,

The cationic polymers of the invention are soluble in water or other solvents, for example, in alcohols in dimethylformamide. The molecular weight and weight will vary widely depending on the reaction and the end use of the product. For example, the reaction products of a prepolymer with mono-tertiary amines can have a molecular weight of 500, while polymers with di-tertiary amines can have molecular weights from 50,000 to 500,000.

The polymeric compounds according to the invention can be used as dewatering, forming, retaining and sizing agents, as well as agents that improve the strength of paper and paperboard, as well as resins. When using these polymers as auxiliary agents in the production of electrically conductive paper, one or more of them can, for example, be continuously added to the papermaking machine at suitable places, for example, to a mass tank, mixing pump or pressure tank, in an amount of 0.05-21% based on the weight of dry pulp. The desired results achieved with these methods can be summarized as follows:

increase in production per unit of equipment;

improved molding and improved strength properties of paper and paperboard;

an increase in overall production efficiency due to a decrease in loss of dyes, short fibers, pigments, fillers, starch and other components, due to the increased retention of these products in paper and cardboard;

alleviation of water pollution problems by the use of polymers in the recovery of chain materials remaining in wastewater from paper and pulp production.

These compounds can also be used to remove dissolved and solid particles remaining in the water before discharge, although such an application is not quite appropriate, since discharges may be biodegradable or incinerated or disposed of according to sanitary rules.

The polymeric compounds according to the invention are also suitable for treating water supplied from supply sources. These compounds are fast-acting flocculants, and in addition to the desired degree of completeness of the removal of finely distributed or dissolved solids, a reduction in the cleaning process time can be achieved. A similar application may be used to remove dissolved and solid particles from industrial or municipal wastewater,

The cationic nature of water-soluble polymers also serves to increase the effectiveness of aqueous adhesion compositions. This is accomplished by using a strong positive charge of the polymers in an electrostatic bonding or by using the non-polar characteristics of bonding the polymers to adhesive materials and surfaces. in fact, they do not carry a sufficiently strong charge to form an electrostatic charge. For example, the adhesive bond of polyethylene to paper is greatly increased by treating the adhesive substance used to make paper with small quantities of the proposed polymers. In the textile industry, the same properties of these polymers as used in the paper industry can be applied in various operations in the processing of cotton textiles. The affinity of polymers for cellulose, as well as for various dyes, pigments and finishes, improves fiber retention, and also improves the leaching resistance of the treated fabric and other processes that reduce the effectiveness of the additives. These polymers are less effective for producing such effects with synthetic fabrics, but still have some utility. In particular, cationic polymers are useful for imparting antistatic properties to synthetic textiles, as well as fabrics made from natural fibers. The destructive effect of microorganisms on organic materials is well known. The elimination or inhibition of the growth of bacteria, fungi and ala has been the subject of many studies and patents. Quaternary ammonium compounds and ionic polymers have proven to be useful for treating water used in various industrial cooling systems and in swimming pools. The cationic polymers of this invention have an effect against bacteria, fungi and algae in aqueous systems, even at very low concentrations. The polymers are effective against microorganisms without causing excessive foaming. Products are easily hydrated, can be diluted with water to any desired concentration. Other advantages of the polymers of this invention are long shelf life, no corrosion, and relatively low toxicity to warm-blooded animals and humans. Concentrations suitable for controlling microorganisms can vary from 0.5 to 500 g per million, based on the weight of the water being treated. Example 1.
