    Abstract: The invention relates to aqueous polymer dispersions for composite film lamination and to a multiple-step method for the production of same from ethylenically-unsaturated, radically polymerisable monomers. In a first step, a first polymer is produced through radical emulsion polymerisation. In a further step, an aqueous polymer dispersion is produced in the presence of the first polymer. The monomers of the first step comprise monomers having acid functional groups. The monomers of the further step comprise monomers having oxazoline functional groups. The polymerisation of the first step occurs at low pH of less than 5. The acid functional groups of the first polymer are neutralised before the polymerisation of the further step. The aqueous polymer dispersions can be used as an adhesive for the production of composite films.

    Abstract: The present invention describes amides of formula (I)
    R 1 -(C=O)-(NR 2 )-R 3
    wherein
    R 1 is a linear or branched, preferably linear C 7 - to C 29 -alkyl, or C 7 - to C 29 -alkenyl, preferably C 7 - to C 23 -alkyl or C 7 - to C 23 -alkenyl
    R 2 is hydrogen or C 1 - to C 4 -alkyl, and
    R 3 is a hydrocarbyl residue comprising 12 to 200 carbon atoms obtainable from polymerisation of an olefin.
    The amides may be used in fuel additive packages or fuels, especially gasoline fuel, as additives for improving the fuel efficiency and/or the fuel economy, for reducing or removing deposits on the intake valves and/or for reducing or removing the fouling of injector nozzles, especially in direct injection spark ignition engines.

    Abstract: Aqueous polymer dispersions and a process for preparing them are described. The polymer dispersions comprise polymer particles having an average diameter of more than 200 nm, a monomodal size distribution and a uniform glass transition temperature and are prepared by radical emulsion polymerization of a monomer mixture comprising ethylenically unsaturated, radically polymerizable monomers, using a polymer seed, less than 0.8 part by weight of emulsifier and no protective colloids. The monomer mixture consists of a) at least 60 wt% of at least one monomer selected from the group consisting of C1 to C20 alkyl acrylates, C1 to C20 alkyl methacrylates, vinyl esters of carboxylic acids containing up to 20 carbon atoms, vinylaromatics having up to 20 carbon atoms, ethylenically unsaturated nitriles, vinyl halides, vinyl ethers of alcohols containing 1 to 10 carbon atoms, aliphatic hydrocarbons having 2 to 8 carbon atoms and one or two double bonds, and mixtures of these monomers, b) at least 0.1 wt% of at least monomer having at least one acid group; c) optionally further monomers, wherein the acid groups of the monomers b) are wholly or partly neutralized during the emulsion polymerization. The aqueous polymer dispersions can be used as an adhesive, particularly for the production of composite films.
