The sequence polymers according to the invention can in fact also be used for the production of "oil-in-water" emulsions if the sequence polymer is soluble in water and yet has a certain affinity for oils.

One of the most characteristic and important properties of the sequence polymers consists in the fact that each of the sequences has the properties of the corresponding homopolymer having. Depending on the choice of sequences, sequence copolymers can be used get, which is hydrophilic and lipophilic at the same time are, but their hydrophilic or lipophilic character is more or less pronounced.

In general, the amount of emulsifier, based on the mixture of oil plus wax, is at least 10 %. The proportion of the oil plus wax mixture, based on the total weight of the emulsion according to the invention, is generally between 20 and 65% by weight .

This production process is essentially characterized in that in a first stage the sequence copolymer is mixed with vigorous stirring and at a temperature of about 150 ° C. with the "oil" phase _; . then after cooling to a temperature of about 80 ° C in a second stage the "water" phase is introduced into the mixture of sequence polymer plus oil-wax with vigorous stirring _3, which is provided with an addition of hydrochloric acid, lactic acid or acetic acid or not and which has previously been brought to the same temperature ₃ after which one. the mixture is cooled to ambient temperature, always with stirring. Finally, the emulsion can be passed through a roller grinder ₅ to refine it. Although the process for producing the sequential polymers is known, the basic steps which lead to their formation are explained again below.

These polymerization reactions, which lead to the formation of sequence polymers, take place in proton-free (aprotic) solvents, such as e.g. B. Benzene ·, Tetrahydrofuran, Toluene and so on. The production of, for example, tri-sequence polymers takes place quite generally as follows :;

First you prepare a solution of the starter = (amorceur) w in the chosen solvent, then you give one

After the end of the polymerization, the trisquence polymer is made using

a few drops of kethanol deactivated. In general, the reaction leading to the formation of these sequential polymers is carried out at a temperature of about -70.degree.

Acids, Amides, etc. VIIf you produce sequential polymers? Iill _. _{If acid functions 3} amide functions, etc. have in one of their sequences, one must therefore start from conomers which can ultimately lead to the formation of a function of this type through chemical reaction. For this purpose it is possible, for example, to start from monomers which have a nitrile function or an ester function. This is because it is possible to obtain the corresponding acids by hydrolysis and finally to obtain the corresponding amides by amidation. Such a procedure can be used if one wants to produce lipophilic sequences made up of methaeryl amide residues or hydrophilic sequences made up of methacrylic acid residues.

In order to better understand "the present invention some examples of embodiments are explained below. The compositions described in the following examples are obtained in each case by mixing the emulsions as described above.
