Hence in practice, because of ease of storage etc., it is desirable to have polymer dispersions which are suitable both for the production of building adhesives and troweling compounds and for the production of plasters and surface coatings, and which in the case of fire do not eliminate any hydrochloric acid which can endanger the fire-fighting team and also cause secondary damage it is an object of the present invention to pro-vise polymer dispersions which give transparent, light-fast hydrolysis-resistant and ~eather-resistant films and which are suitable for the production of water-resistant hydrolysis-resistant flame-retardant adhesives and troweling compounds which may or may not contain cement and which exhibit strong adhesive interactions both with - mineral building materials, ego concrete and mortar, and I ugh polystyrene-based foams. They should, however, also be suitable for the production of water-resistant hydrol-ysis-resistant weather-resistant flame-retardant plasters and surface coatings which are stable to yellowing In particular, they should be suitable for full heat-insulation systems, to. for attaching and coating heat-insulating sheets in the insulation of buildings and should not eliminate any hydrogen chloride during a fire.
We have found that this object is achieved, and that halogen-free emulsion copolymers of monoolefinically unsaturated carboxylatesr which contain, as copolymerized units, a) from 55 to 72 X by weight of vinyl preappoint, _ 3 - OOZE. 0050/36141 b) from 44.9 to 27.5 X by weight so ~ert.-butyl acrylate, c) from 0.1 to 0.5 % by weigh of acrylic acid or methacrylic acid and d) from 0 to 17.5 X by wright of a monoolefini-gaily unsaturated carboxylate from the group comprising vinyl acetate, methyl acrylate and methacrylate, n- and ;so-butyl acrylate and methacrylate and dibutyl Malta, the percentages being based on the total amount of the monomers, can be particularly advantageously used as binders for building adhesives, trillion compounds and plasters, on particular for full- heat-insulation soys-terms.

The building adhesives which are based on the aqueous dispersions prepared by emulsion copolymeri~a~ion of the monomers to d) and continuing the dispersants en to g) can Allah be advantage-ouzel used for bonding tiles; they can be particularly advantageously used for bonding heat-insulat;ng sheets, for example those based on styrenes polymers as jell as cellular glass sheets cork sheets, foam-s;licate ions-tong sheets, rigid expanded polyurethane sheets and mineral-based fibrous insulating materials sup h as fluffy wool and rock wool. They can also be used as binders for '' - 4 - OOZE. 0050/36141 surface coatings.
The emulsion copolymers are prepared in a convent tonal manner from the monomers a) to d), in general water-soluble polymerization initiators, in particular ammonium peroxydisulfate or potassium peroxydisulfate or ! sodium peroxydisulfate, and conventional redo catalysts comprising hydrogen peroxide or tert.-butyl hydroperoxide as the oxidizing component and sodium formaldehyde-sulfoxylate as the reducing component being employed.
The polymerization temperature can be varied within a Dow range, but us in general from ox to 85C. The total amount of the monomers us preferably from 50 to I X by weight, based on the total amount of monomers, d;spersants and Atari To reduce the amount of residual monomers, it us advantageous, after polymerization is complete to add a further amount of catalyst and continue the polymerize-ton. The resulting dispersions generally have light-permeability values of from 40 to 7G X, preferably from 50 to 6û X, and a minimum film-~ormation temperature of from 2û 8 to 23C, preferably from 12 to 18C. In general, they have a pi of from 6 to 9.5, preferably from 7 to 8~5. The pi can be adjusted-- by adding ammonia In the oxyethylated alkylphenols e), the alkyd radicals are preferably n- or isooctyl or n- or isononyl.
The compounds contain in general from to 40~ preferably from 20 to 30, ethylene oxide radicals per molecule. The sulfated oxyethylated alkylphenols likewise preferably have n- or isooctyl or n- or isononyl groups as alkyd radicals, and likewise contain in general from 8 to 40, preferably from 20 to 30, ethylene oxide radicals per molecule. They can, of appropriate, be employed in the form of their alkali metal salts in particular their sodium salts Suitable cellulose ethers g) are methoxymethyl-cellulose, ethoxymethylcellulose and hydroxyethylcellu-lose, preferably the las~-ment;oned.

The cement-ccntaining building adhesives and Roy-cling compounds prepared in an otherwise conventional manner using the polymer dispersions of the above type have a processing time of in general from 4 to 6 hours, set rapidly after application, and, particularly on ox-panted polystyrene and on mineral substrates, develop very good adhesion values, which are not substantially affected even by the action of water.
To prepare adhesives, troweling- compounds, plasters and surface coatings using the polymer dispersions of the above type, the assistants, f; tiers and pigments usually used for this purpose and the conventional mixing appear-tusks can be employed. The adhesives, ~rowe~n~--compounds, plaster and surface coatings can be processed in a con-ventional manner, and in general can contain the polymer dispersions of the above type as the only bonders.

Claims (2)
PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:
1. A binder for building adhesives, troweling com-pounds and plasters which is based on a halogen-free emul-sion copolymer of monoolefinically unsaturated carboxy-lates, wherein the said copolymer comprises a) from 55 to 72 % by weight of vinyl propionate, b) from 44.9 to 27.5 X by weight of tert.-butyl acrylate, c) from 0.1 to 0.5 % by weight of acrylic acid or methacrylic acid, and d) from 0 to 17.5 % by weight of a monoolefini-cally unsaturated carboxylate from the group comprising vinyl acetate, methyl acrylate and methacrylate, n- and isobutyl acrylate and methacrylate and dibutyl maleate, the percentages being based on the total amount of the monomers.
2. A binder as claimed in claim 1, which is prepared by copolymerization of monomers (a), (b) and (c), with or without (d), in aqueous emulsion in the presence of e) from 1.5 to 4 % by weight of an oxyethylated alkylphenol where alkyl is of 8 or 9 carbon atoms, f) from 0.75 to 3 % by weight of a sulfated oxy-ethylated alkylphenol where alkyl is of 8 or 9 carbon atoms and g) from 0.1 to 0.5 % by weight of a cellulose ether, the percentages being based on the total amount of the monomers, and the total amount of the monomers being from 35 to 65 % by weight, based on the sum of the amounts of monomers, dispersants and water.
