  The process for preparing the polymer of this invention is now explained in detail.  
  The starting material (II) used in the present invention may be any of the tertiary diamines and includes, for example, 1,4-dimethylpiperazine, triethylenediamine, N ,N,N,N-tetramethylethylenediamine, N,N- ,N&#39;,N-tetramethylpropylenediamine, N,N,N,N&#39;- tetramethylhexamethylenediamine, N,N,N&#39;,N&#39;-tetramethylxylylenediamine, bis(B-N,N-dimethylaminoethoxy)ethane and the like; and N,N,N&#39;,N&#39;-tetramethylethylenediamine, N,N,N&#39;,N&#39;-tetramethylhexamethylenediamine, and bis(B-N,N-dimethylaminoethoxy)ethane are preferred materials economically.  
  The second starting material (III) is obtained by the reaction of monohaloacetic acid with an appropriate glycol and includes, for example, bis(chloroacetyl- )ethylene glycol, bis(chloroacetyl)-l ,4-butanediol, bis- (ch1oroacetyl) l l O-decanediol, bis(chloroacetyl)cyclohexanediol, bis(chloroacetyl)xylylene glycol, bis(- chloroacetyl)-butyndiol, -bis(chloroacetyl)butenediol, bis(chloroacetyl)-2,3-butanediol, bis(chloroacetyl) polyethylene glycol, bis(chloroacetyl)-1,3- propanediol, and the like.  
  The third starting material (IV) includes, for example, 2,4,6-tris(N,N-dimethylaminomethyl)phenol, 1,1,- 3-tris(B-N,N-dimethylaminoethoxy)propane, tetrakis(- B-N,N-dimethylaminopropionyl)pentaerythritol, tris(- B-N,N-dimethylaminopropionyl)trimethylolpropane, tris(B-N,N-dimethylaminopropionyl)glycerol, and the like.  
  The fourth starting material (V) includes, for example, tetrakis(chloroacetyl)pentaerythritol, tris(chloroacetyl)trimethylolpropane, tris(chloroacetyl)-glycerol, chloroacetylated sorbitols and glucose, and the like.  
  The process for preparing novel polymers of this invention comprises dissolving the above-mentioned compounds (11) and (Ill) together with compound (IV) in an amount corresponding to several mole percent, preferably less than mole percent, of compound (II) or compound (V) in an amount corresponding to several mole percent, preferably less than 10 mole percent, of compound (III), or compound (IV) in an amount corresponding to several mole percent, preferably less than 10 mole percent, of compound (II) and compound (V) in an amount corresponding to several mole percent, preferably less than 10 mole percent, of compound (III) in an organic solvent such as methanol, ethanol, acetone, ethyl acetate, tetrahydrofuran, methyl ethyl ketone, acetonitrile, benzene, cyclohexane, toluene, chloroform, cyclohexanone, tetrahydrothiophene-l,l-dioxide (sulfolane), N,N-dimethyl formamide or a mixture thereof and heating the solution at a temperature between 0C and a refluxing temperature inclusively, preferably between 10 and 50C inclusively to conduct the reaction.  
  In order to smoothly carry out the reaction and obtain the product in high degree of polymerization and in high yield, it is necessary to employ the reactant compounds in a proportion that the ratio of the number of the whole functional groups of compounds (II) and (IV) and that of compounds (III) and (V) is 1:1. For instance, suppose that a moles of compound (II) and b moles of compound (III) are used together with 0 moles of compounds (IV) of which the number of the functional groups is p and d moles of compound (V) of which the number of the functional groups is q, then the relation is expressed by the following equation:  
 In the process of this invention, in addition to the reaction between compound (II) and compound (Ill), reactions partly take place between compound (II) and compound (V), between compound (III) and compound (IV) as well as between compound (IV) and compound (V). Therefore formation of polymers of lower degree of polymerization, caused by termination of propagation, which is a common phenomenon in the field of polymer chemistry, is prevented and thus prod ucts of high degree of polymerization are obtained.  
  Molecular weight of the products of this invention is normally in the range of from several tens of thousands to two hundreds of thousands. The molecular weight of the polymer product of Example 16 as described hereinafter was approximately about 6.5 X 10 when it was determined by the light-scattering measurement after purification by reprecipitating the product.  
  It is commonly observed in polymerization reactions of polyfunctional monomers such as compounds (IV) and (V) that cross-linking occurs to develop reticular structure resulting in formation of insoluble polymers. Such tendency is observed in the process of this invention, too, especially when the tetrahydrothiophene-l ,ldioxide (sulfolane), N,N-dimethylformamide, and the like are used as a solvent. These solvents dissolve lowmolecular weight polymers and therefore reactions proceed between the low-molecular polymers and the reactant compounds and/or between the low-molecular polymers per se giving polymers of high degree of polymerization, sometimes insoluble polymers.  
  The starting materials (111) and (V) used in the process of this invention are extremely reactive owing to the halogen atoms attached to the a-positions to the carbonyl groups and give polymers of high degree of polymerization degree in a high yield even under rather mild conditions. This fact makes it possible to employ less reactive chlorideas the quaternarizing agent in place of iodide and bromide which have been the halide of choice in the conventional quaternarizing reaction because of their higher reactivity though they are disadvantageous in handling and cost. It is one of the remarkable features of this invention that, by utilizing chloride, which is easily available and handled, the polymers of high degree of polymerization can be obtained without the risk which is accompanied with the use of iodide or bromide.  
  The polymers of this invention are a novel cationic polyelectrolite containing quaternary ammonium salt portions in its molecule.  
  One characteristic of this polyelectrolyte is that, when it is added to turbid sewage or drainage water in relatively small amounts, the water is clarified by, unlike the conventional nonionic or anionic polyelectrolyte, neutralizing the negative zeta-potential of microparticles suspended therein thereby flocculating and sedimenting the particles, and that this polyelectrolyte can effectively be used for such a purpose over the wide range of pH value because it will not be in an insoluble state over that pH value.  
  The invention is now illustrated by way of working examples of preparation and experiments showing effect of the products. These are only for the better understanding of this invention and are never intended to limit the invention thereto.  
  The attached FIGURE is a diagram showing the coagulating effect of the polymer of this invention in comparison with that of the conventional coagulants.  
 EXPERIMENT l 0.1 g of crystalline sericite, the particle size of which is 2 u or less in diameter, was added to 1 liter of water and vigorously agitated. The resulting suspension was formed to be stable and had not cleared even after being allowed to stand for 1 week.  
  To this suspension, 0.3 mg of a polymer prepared in Example 7 described hereinafter was added, and the suspension was thoroughly stirred with a magnetic stirrer. The turbidity of the suspension was periodically determined with a turbidimeter.  
  The same test was carried out with respect to aluminium sulfate and sodium alginate, which are typical conventional coagulating agents. The results are shown in the FIGURE.  
 1n the drawing:  
  The curve E] indicates the control sample in which no coagulating agent was used; the curve -A indicates a sample in which ppm of sodium alginate was added; the curve O stands for a sample in which 180 ppm of aluminium sulfate was added; and the curve O indicates a sample in which 3 ppm of the polymer of Example 7 was used. in all these tests, pH of the suspension was 7.0.  
 EXPERIMENT 2 When granulated crystalline sericite, the particle size of which is 10-40u in diameter, is suspended in water at a level of 0.5 percent or less the sedimentation takes place extremely slowly. To such stable suspensions that do not exhibit rapid spontaneous sedimentation, the polymers of this invention prepared in Examples 1, 2, 6, 7, 8, l2, l3 and l4 were added, and it was revealed that they have good sedimentation-promoting effect. The results are summarised in Table l.
