Definitions

  • the invention relates to a process for the preparation of epoxy-modified vinyl chloride-vinyl ester copolymer solid resins and to the use thereof, in particular in coating resin compositions.
  • Vinyl chloride copolymers containing epoxy groups are used as binders in coatings. Their use in heat-seal coatings, for example, for aluminum coating, should be singled out.
  • Epoxy-containing vinyl chloride-vinyl acetate copolymers are well established but are obtainable only as solutions, for example in toluene and/or methyl ethyl ketone. For the user, this has the disadvantage that the choice of the solvent in which the coating resin is applied is greatly limited, for example to the solvent in which the coating resin is offered, or to solvents compatible therewith.
  • an object of the invention is to provide epoxy-modified vinyl chloride-vinyl ester copolymers in the form of solid resins. This and other objects are achieved by a process in which vinyl chloride is copolymerized with epoxy group-containing comonomers and vinyl ester comonomers in the presence of aldehyde molecular weight regulators.
  • the invention relates to a process for the preparation of epoxy-modified vinyl chloride-vinyl ester copolymers in the form of solid resins obtainable by means of aqueous, free radical polymerization of a mixture comprising
  • Suitable epoxide-containing vinyl monomers b) are, for example, methylglycidyl methacrylate, methyl glycidyl acrylate, allyl glycidyl ether, allylphenol glycidyl ether and glycidyl methacrylate.
  • Glycidyl methacrylate (GMA) is preferred.
  • Preferred vinyl ester monomers c) are those of carboxylic acids having 1 to 12 carbon atoms.
  • Vinyl acetate is most preferred.
  • Preferably from 5 to 15% by weight of the vinyl ester monomers c), in particular vinyl acetate, are copolymerized.
  • Suitable further copolymerizable comonomers d) include one or more ethylenically unsaturated monomers from the group of acrylates or methacrylates of branched or straight-chain alcohols or diols having 1 to 18 carbon atoms, and ethylenically unsaturated mono- and dicarboxylic acids and anhydrides thereof.
  • Preferred monomers from the group consisting of acrylates or methacrylates are esters of straight-chain or branched alcohols having 1 to 15 carbon atoms.
  • Particularly preferred methacrylates or acrylates are methyl acrylate, methyl methacrylate, ethyl acrylate, ethyl methacrylate, propyl acrylate, propyl methacrylate, n-butyl acrylate, n-butyl methacrylate, tert-butyl acrylate, tert-butyl methacrylate and 2-ethylhexyl acrylate.
  • Methyl acrylate, methyl methacrylate, n-butyl acrylate, tert-butyl acrylate and 2-ethylhexyl acrylate are most preferred.
  • Suitable ethylenically unsaturated mono- and dicarboxylic acids and anhydrides thereof are acrylic acid, methacrylic acid, fumaric acid, itaconic acid, crotonic acid, maleic acid and maleic anhydride.
  • the free radical polymerization is effected by means of suspension polymerization.
  • the polymerization temperature is in general from 20° C. to 80° C.
  • the initiation of the polymerization can be effected with the customary water-soluble or monomer-soluble initiators or redox initiator combinations.
  • water-soluble initiators are the sodium, potassium and ammonium salts of peroxoydisulfuric acid.
  • monomer-soluble initiators are dicetyl peroxydicarbonate, dicyclohexyl peroxydicarbonate, dibenzoyl peroxide and tert-butyl peroxypivalate.
  • the initiators are used in general in an amount of from 0.01 to 1.0% by weight, preferably from 0.1 to 0.5% by weight, based in each case on the total weight of the monomers.
  • polymerization is effected in water in the presence of surface-active substances such as protective colloids and/or emulsifiers.
  • Suitable protective colloids are, for example, partly hydrolyzed polyvinyl alcohols and cellulose ethers.
  • Suitable emulsifiers are anionic, cationic and nonionic emulsifiers, for example anionic surfactants such as alkylsulfates having a chain length of from 8 to 18 carbon atoms, alkane- or alkylarylsulfonates having from 8 to 18 carbon atoms, ester and monoesters of sulfosuccinic acid with monohydric alcohols or alkylphenols, or nonionic surfactants such as alkylpolylglycol ethers or alkylarylpolyglycol ethers having up to 60 ethylene oxide or propylene oxide units.
  • anionic surfactants such as alkylsulfates having a chain length of from 8 to 18 carbon atoms, alkane- or alkylarylsulfonates having from 8 to 18 carbon atoms, ester and monoesters of sulfosuccinic acid with monohydric alcohols or alkylphenols, or nonionic surfactants such as al
  • 0.001 to 0.1% by weight preferably from 0.005 to 0.05% by weight of ascorbic acid and/or isoascorbic acid, based in each case on the total weight of the comonomers, are optionally added during or after the polymerization.
  • Ascorbic acid is preferably used. The addition is preferably effected after the end of the monomer metering and before, during or after the removal of residual monomers.
  • citric acid is also added in addition to ascorbic acid and/or isoascorbic acid is most preferred.
  • the amount of citric acid is from 0.001 to 0.1% by weight, preferably from 0.005 to 0.05% by weight, based in each case on the total weight of the comonomers.
  • regulating substances are used during the polymerization.
  • the regulators are used in amounts of from 0.02 to 10.0% by weight, based on the monomers to be polymerized, and are metered separately or in a form premixed with reaction components.
  • Suitable regulators are aldehydes such as acetaldehyde, propionaldehyde, butyraldehyde and isobutyraldehyde.
  • Polymerization is preferably effected in the presence of propionaldehyde.
  • propionaldehyde Compared with other regulators such as, for example, trichloroethylene, propionaldehyde has the advantage that a regulating effect is achieved even with small amounts. It is therefore preferably added in an amount of from 0.02 to 5% by weight, based on the monomer, depending on the desired molecular weight.
  • the monomers can be metered in together or can be initially introduced in portions and the remainder metered in after initiation of the polymerization.
  • the meterings can be carried out separately (with respect to space and time), or some or all of the components to be metered can be metered in preemulsified form.
  • postpolymerization can be effected for removing residual monomers with the use of known methods, for example by postpolymerization initiated by a redox catalyst.
  • Volatile residual monomers can also be removed by means of distillation, preferably under reduced pressure, and optionally by passing inert entraining gases such as air, nitrogen or steam, through or over the reaction mixture.
  • the epoxy-modified vinyl chloride-vinyl ester copolymers can be isolated from the aqueous dispersion in the form of solid resin by means of customary methods, by precipitation, filtration and subsequent drying, or by means of decanting and subsequent drying.
  • the drying can be effected in a manner known to those skilled in the art, for example in a tumble drier, in a flow tube, in a fluidized bed, or in a cyclone drier.
  • the epoxy-modified vinyl chloride-vinyl ester copolymers are distinguished by high blocking resistance up to 180° C., and by high chemical resistance to solvents, acids and bases.
  • the epoxy-modified vinyl chloride-vinyl ester copolymers in the form of their solid resins are suitable, for example, as adhesives, in particular for the adhesive bonding of security features in banknotes or plastic cards, and as binders for coatings, for example for aluminum coatings.
  • a copolymer comprising 82% by weight of vinyl chloride, 9% by weight of vinyl acetate and 9% by weight of glycidyl methacrylate was prepared by the suspension polymerization process, the comonomers having been completely initially introduced before initiation of the polymerization. After the end of the polymerization, the batch was let down to atmospheric pressure, and 0.05% by weight of ascorbic acid was added. Thereafter, demonomerization was effected and the copolymer was filtered, washed and dried. A white, flowable powder was obtained.
  • a copolymer was prepared from 82% by weight of vinyl chloride, 9% by weight of vinyl acetate and 9% by weight of glycidyl methacrylate by the emulsion polymerization process. At the end of the reaction, the mixture was let down to atmospheric pressure and 0.02% by weight of ascorbic acid and 0.0025% by weight of citric acid, based in each case on the total weight of the comonomers and in each case as a 10% strength aqueous solution, were added to the batch. Thereafter, demonomerization was effected and the copolymer was precipitated, filtered, washed and dried. A white, flowable powder was obtained.
