    Abstract: PROBLEM TO BE SOLVED: To obtain an adhesive capable of being used for laminating lustous films by adding the aqueous dispersion of a polymer comprising a main monomer, an ethylenic unsaturated acid having a metal salt, and one or more other monomers in a specific ratio. SOLUTION: This adhesive contains the aqueous dispersion of a polymer formed from radically polymerizable compounds as a binder. Therein, a monomer in an amount of 0.1-20 wt.% based on the total amount of the monomers is an ethylenic unsaturated acid, and at least 20 mol.% of the acid group exist in the form of at least divalent metal (preferably Ca, Zn of Mg) salt. The polymer preferably comprises (A) 20-99.9 wt.% of a main monomer selected from 1-20C alkyl (meth)acrylates,

    Abstract: PROBLEM TO BE SOLVED: To obtain a laminated product composed of e.g. a high-gloss film and a paper with good adhesiveness by using an aqueous dispersion of a polymer made from a main monomer such as specific alkyl acrylate or alkyl methacrylate, a submonomer such as ethylenic unsaturated acid, and other monomer(s). SOLUTION: This laminated product by mutually bending large-area base materials is obtained by using a polymer as an adhesive which is prepared from (A) 5-95 wt.% of a 4C alkyl acrylate, (B) 5-95 wt.% of a 1-2C alkyl acrylate, (C) 0-50 wt.% of a main monomer selected from 1-2C alkyl methacrylates, 4C alkyl methacrylates, 3C and 5-16C alkyl (meth)acrylates, and vinyl aromatic compounds and others, (D) 0-20 wt.% of a submonomer selected from ethylenic unsaturated acids, acids anhydrides, ethylenically unsaturated nitriles or amido-and hydroxyl-contg. ethylenically unsaturated compounds, and (E) 0-20 wt.% of other monomer(s).

    Abstract: Laminates are produced by bonding substrates of large area with an aqueous adhesive dispersion of a polymer of 5-95 wt.% 4C alkyl acrylate, 5-95 wt.% 1 or 2C alkyl acrylate and optionally other monomer(s). The other monomers are 0-50 wt.% primary monomers, selected from 1-2C alkyl methacrylate, 4C alkyl methacrylates, 3 and 5-16C alkyl (meth)acrylates, vinyl aromatics and ester esters of carboxylic acids containing ≤ 20C; 0-20 wt.% secondary monomers, selected from ethylenically unsaturated acids, anhydrides, nitriles, amides and hydroxyl compounds; and 0-20 wt.% other monomers. An Independent claim is also included for (a) the production of the laminates by bonding with this adhesive.

    Abstract: In the production of aqueous polymer dispersions by free radical emulsion polymerisation of monomers, a mini-emulsion (I) is added before or during polymerisation. (I) is an aqueous emulsion, stabilised with a surfactant, which contains emulsified monomer droplets with a particle size of 10-500 nm and a co-stabiliser, dissolved in the monomer, which is at least twice as soluble in the monomer as it is in water. Also claimed are polymer dispersions obtained in this way.

    Abstract: The present invention relates to a method for the manufacture of low viscosity aqueous polymer dispersions with a polymer content of more than 50 vol. % and a polymodal distribution of polymer particle sizes by radical, aqueous emulsion polymerization of ethylenically unsaturated monomers, comprising at least one monomer (A) selected from monomers having a neutral functional group, which can be converted, according to Ph-value of reaction mixture, into a charged functional group and C1-C2 alkyl esters of monoethylenely unsaturated monocarboxylic or dicarboxylic acids. The invention also relates to polymer dispersions obtained according to this method.

    Abstract: Microcapsules which are composed of a core and of a shell of a polymer, the core containing at least one oil which can be emulsified in water, and which are obtainable by polymerization of oil-soluble monomer mixtures which contain (a) 1-100% by weight of acrylic anhydride, methacryic anhydride, itaconic anhydride, citraconic anhydride, dimethylmaleic anhydride, 4-vinylbenzoic anhydride, mixed carboxylic anhydrides, mixtures of the said anhydrides and/or more than 40% by weight of maleic anhydride, (b) 0-99% by weight of at least one monoethylenically unsaturated monomer which is different from the monomers of group (a), (c) 0-80% by weight of crosslinking monomers which have at least two monoethylenically unsaturated non-conjugated double bonds in the molecule, and (d) 0-20% by weight of water-soluble monoethylenically unsaturated monomers in the oil phase of a stable oil-in-water emulsion in the presence of polymerization initiators which form free radicals, where the temperature of the polymerizing reaction mixture may be continuously or periodically increased during the polymerization, a process for producing the microcapsules by polymerization of the abovementioned monomer mixtures in the oil phase of a stable oil-in-water emulsion in the presence of polymerization initiators which form free radicals, where the temperature of the polymerizing reaction mixture may be continuously or periodically increased during the polymerization, and the use of the microcapsules for the controlled release of the core material of the microcapsules as active substance by destruction of their shell, in particular by the action of bases.
