Plastics are mainly colored either by mass coloring in the manufacture of the plastics or in the processing of plastic powders or granulates. The coloring process is adapted to the respective plastic.
- the colorant concentrates should have good solubility in the monomer or in prepolymers. They should also not adversely affect the course of polymerization and the demolding of the products from the glass plates of the mold.
- the pigments should be well dispersed in the polymerization batches and, above all, the disperse state of the pigments must be sufficiently stable, i.e. H. there must be no sedimentation or re-agglomeration of the pigments.

- R ' 3 R' N - X - Y group where X is a linear or an optionally branched, optionally cyclic alkylene group having 2 to a total of 10 carbon atoms, Y is oxygen or a radical -NR 5 - and R ' 3 and R ' 4 have the same meanings as R 3 and R 4 and R 5 represents hydrogen or an alkyl radical having 1 to 6 carbon atoms or
- X "and Y" have the same meanings as X and Y, n is zero or one and R ⁇ is hydrogen or an alkyl radical having 1 to 6 carbon atoms,
- the syrup according to the invention can be processed and dispersed very well together with all pigments known per se.
- the colorants used to prepare the colorants are also suitable for coloring the polymers, ie. H. both inorganic and organic dyes or pigments or nanoparticles. They can be taken from the prior art based on the plastics to be colored (see Vieweg-Esser, Kunststoff-Handbuch, Volume IX, 'Polymethacrylate', C. Hansen Verlag 1975).
- pigments are e.g. B. carbon blacks, iron oxide, titanium dioxide, phthalocyanine blue and green dioxazine and quinacridone-like pigments.
- the concentration of the colorants in the syrup according to the invention is generally 10-70% by weight, preferably 30-60% by weight and particularly preferably 40-50% by weight, based on the mass of the syrup.
- the colorants are incorporated into the syrup according to the invention by means of the customary processes which are known in the prior art.
- the proportion of the master batch in the total batch is generally between 0.05 and 10% by weight, preferably between 0. 1 and 5 wt .-% and particularly preferably between 0.5 and 3 wt .-%.

- the subsequent processing steps for example the filling of the syrup into the shaping polymerization chambers and the subsequent polymerization step can then be carried out analogously to the prior art method, likewise the subsequent demolding of the finished polymer plates.
- Acrylic resins are generally made up entirely or in large part of esters of acrylic and methacrylic acid, in particular methyl methacrylate (MMA) as monomers, if appropriate in addition to MMA, from other copolymerizable monomers.
- MMA methyl methacrylate
- the matrix polymers based on methyl methacrylate can, for. B. still contain proportions of 0 to about 45 wt .-% of other comonomers.
- esters of methacrylic acid or acrylic acid such as. B. the acrylic acid methyl ester, acrylic acid butyl ester, ⁇ -chloroacrylic acid methyl ester, methacrylic acid ethyl ester; further (optionally substituted) amides of acrylic or methacrylic acid, such as acrylamide and methacrylamide, methylol methacrylamide and acrylamide.

- Impact modifiers can also be used.
- the polymerization can be carried out in a manner known per se, using the experience of technology (cf. H. Rauch-Puntigam and Th. Völker in "Acryl- und Methacrylitatien", Springer-Verlag 1967 and J. Brandrup - EH Immergut, Polymer Handbook, 2nd Edition, Wiley-Interscience (1975), the basic features of which have already been described in DE-PS 639 095.
- Peroxide or azo compounds for example, can be used in the usual amounts as initiators for the radical polymerization of the monomers (such as the acrylic monomers, styrene and derivatives, esters of vinyl compounds).
- the known regulators and / or retarders in the known concentrations are suitable for controlling the molecular weight. May be mentioned for.
- the degree of polymerization and thus the molecular weight of the resin molecules formed can be adjusted, as is known, by the initiator concentration and / or the regulator concentration. So you will usually use 0.01 to 1.0 wt .-% of initiator in the polymerization of acrylic resins.
- regulator and / or retarder is generally between 0.01 and 0.5% by weight, preferably between 0.05 and 0.2% by weight.

- half of the solution is placed in the cooking container.
- the second half remains in the feed tank.
- the cooking process is started in automatic mode.
- the solution is heated to 73 ° C. At this temperature, the inflow of the second half of the Solution from the inlet tank between 18 l / min. and 30 I / min. The temperature should not exceed 93 ° C.
- the coolant is drained.
