    摘要: The invention relates to a method for producing an aqueous polymer dispersion having a polymer solids content of >/= 50 % by weight by carrying out the radically initiated aqueous emulsion polymerization of ethylenically unsaturated compounds (monomers). The inventive method is characterized in that: a) a mixture is provided in a polymerization vessel and contains a partial quantity 1 consisting of: deionized water, 0.001 to 0.5 parts by weight of a polymer with a weighted average particle diameter of /= 80 % [polymerization step A], and; b) afterwards, a monomer emulsion containing partial quantity 2, which consists of deionized water, 0.1 to 5 parts by weight of dispersants and 90 to 99.5 parts by weight of monomers, is fed under polymerization conditions to the obtained reaction mixture [polymerization step B], whereby; c) the total amount of the monomers used for the polymerization is equal to 100 parts by weight, and the total amount of deionized water is

    摘要: The invention relates to the use of fine-particle polymer powders, containing at least one UV absorber for the stabilisation of polymers, in particular, polyolefins, against the effects of UV radiation. The invention further relates to stabiliser mixtures for the stabilisation of polymers against the effects of UV radiation, oxygen and heat, comprising, amongst others, said polymer powders and a method for the stabilisation of polymers, in particular, polyolefins against the effects of UV radiation, oxygen and heat, characterised in that effective amounts of said stabiliser mixtures are added to the polymers, in particular, the polyolefins. Furthermore, the invention relates to polymers stabilised against the effects of UV radiation, oxygen and heat, in particular, polyolefins, which comprise an effective amount of said polymer powders or stabiliser mixtures and objects produced from said stabilised polymers in particular, polyolefins.

    摘要: The invention relates to a method for producing an aqueous polymer dispersion having a polymer solids content of ≥ 50 % by weight by carrying out the radically initiated aqueous emulsion polymerization of ethylenically unsaturated compounds (monomers). The inventive method is characterized in that: a) a mixture is provided in a polymerization vessel and contains a partial quantity 1 consisting of: deionized water, 0.001 to 0.5 parts by weight of a polymer with a weighted average particle diameter of ≤ 100 nm; 0.0001 to 0.1 parts by weight of dispersants, and 0.5 to 10 parts by weight of monomers, and the monomers are polymerized with a conversion of ≥ 80 % [polymerization step A], and; b) afterwards, a monomer emulsion containing partial quantity 2, which consists of deionized water, 0.1 to 5 parts by weight of dispersants and 90 to 99.5 parts by weight of monomers, is fed under polymerization conditions to the obtained reaction mixture [polymerization step B], whereby; c) the total amount of the monomers used for the polymerization is equal to 100 parts by weight, and the total amount of deionized water is ≤ 100 parts by weight.

    摘要: The invention relates to combinatory methods for producing an array of n aqueous polymer dispersions by emulsion polymerization and for producing an array of m formulations of polymer dispersions, in addition to the arrays themselves. The methods are carried out at n or m spatially separated locations for the n or m formulations. To carry out the emulsion polymerization, monomers, an initiator, a dispersant and optionally additional components are reacted with one another in water, which acts as the reaction medium. To produce the formulations, aqueous polymer dispersions are mixed with other aqueous polymer dispersions and/or additional components. In all methods, each one of the n or m formulations differs from the other formulation in at least one respective parameter, which can influence the characteristics of the polymer dispersions or formulations that are obtained. The advantage of the invention is that said method allows a large number of aqueous polymer dispersions and formulations to be produced and characterized. This accelerates the development of aqueous polymer dispersions and formulations with optimized characteristics.
