The present invention relates to the stabilization of (meth)acrylic monomers against premature polymerization during synthesis, storage and transport. The term '(meth)acrylic monomers' is understood to mean derivatives both of methacrylic acid and of acrylic acid.

Stabilized (meth)acrylic monomers

The invention relates to a method for producing methacrylated benzophenones and to the uses thereof.

Method for producing methacrylated benzophenones

The invention describes a composition comprising, in the form of aqueous dispersion, A) for every 100 parts by weight of a, or of a plurality of, (meth)acrylate polymer(s); B) from 1-400 parts by weight of a, or of a plurality of, (meth)acrylate polymer(s), which contain(s) a compound of the formula (I) copolymerized, where the (meth)acrylate polymer(s) B) differ from the (meth)acrylate polymers specified in A), where these are obtainable by emulsion polymerization of a mixture comprising  Dispersions of this type are UV-curable and have excellent suitability for the production of coatings of any type, in particular for coating of mineral substrates, such as concrete. The dispersions of the invention are also advantageous for blending with known dispersions and improve their properties, in particular in respect of their curing profile.

Composition comprising as the aqueous dispersion preferably (meth)acrylate polymers containing benzophenone in a mixture with (meth)acrylate polymers different therefrom and the use of said composition

The present invention relates to a coating composition comprising at least one photo-initiator and at least one (meth)acryl-polymer having units that are derived from (meth)acryl-monomers that have at least one double bond and 8 to 40 carbon atoms in the alkyl residue. The present invention furthermore relates to a monomer mixture comprising at least one (meth)acryl-monomer having at least one double bond and 8 to 40 carbon atoms in the alkyl residue and at least one photo-initiator monomer and a (meth)acryl-polymer that can be obtained by polymerization of said monomer mixture. The present invention furthermore relates to a method for producing a coating. The present invention furthermore relates to a coated object comprising a coating obtained by said method.

Coating composition, (meth)acrylic polymer and monomer mixture for producing the (meth)acrylic polymer

The present invention relates to a (meth)acrylate monomer of the general formula (I) in which Ris hydrogen or a methyl group, X is oxygen or a group of the formula NR' in which R&#x2032; is hydrogen or a radical having 1 to 6 carbon atoms, Ris an alkylene group having 1 to 22 carbon atoms, Y is oxygen, sulphur or a group of the formula NR&#x2033;, in which R&#x2033; represents hydrogen or a radical having 1 to 6 carbon atoms, and Ris an unsaturated radical having 8 carbon atoms and at least two double bonds. The present invention further relates to a process for preparing the monomers set out above, to polymers obtainable from this monomer mixture, and to coating materials which comprise the stated polymers.

(Meth)acrylate monomer, polymer and coating agent

The present invention relates to an emulsion polymer comprising at least one (meth)acrylate segment which comprises

Emulsion polymers, aqueous dispersions and method for producing the same

The present invention relates to an aqueous dispersion comprising at least one alkyd resin and at least one addition polymer having at least one (meth)acrylate segment which comprises
