摘要： In the process and a correspondingly appropriate device for preparing homo- or copolymers of at least one of the, polymerizable monomers of the group consisting of styrene, butadiene, vinyl chloride, vinyl acetate, vinylidene chloride, alkyl (meth)acrylatc (meth)acrylic acid, (meth)acrylonitrile and (meth)acrylamide reaction is carried out at at least 40° C. in the presence of a dispersing auxiliary and of a free-radical polymerization initiator such that at least 85% by weight of the polymer is formed from these monomers. In the multistage process the procedure is such that a) in a first stage water is added as a solvent which is inert in the reaction and dispersing auxiliaries, seed and a first portion of monomer(s) are added if desired, b) in a second stage initiator is added, and c) in a third stage the remainder or all of the monomer(s) is added directly or in emulsion form and in the presence of further water and, if desired, further dispersing auxiliary or other auxiliaries, it also being possible to operate any two of the stages as a single stage. The reaction mixture, which is in emulsion form, is moved in all or some stages through an external circuit which leads from and back to the reaction vessel (2) and comprises at least one low-shear pump (7) and at least one heat exchanger (8) having an essentially laminar flow profile. The products prepared by this process, which involves short preparation times, have good performance properties (for adhesive bonds, for example).

摘要： A process for preparing polymer dispersions of at least one of the polymerizable monomers from the groups consisting of alkyl (meth)acrylates, vinyl esters of carboxylic acids having 1-20 carbon atoms, vinylaromatic compounds, nitrites, vinyl halides, vinyl ethers, hydrocarbons having 2-8 carbon atoms, and hydroxyl-containing monomers in emulsion polymerization technology at a polymerization temperature of at least 40° C., in the presence of a free-radical polymerization initiator, which comprises preparing the polymer, which forms to at least 85% by weight from one or more of these monomers. In a first stage, water, as reaction-inert solvent, dispersing assistants where appropriate, seed where appropriate, and a first portion of monomer(s), where appropriate, are introduced. In a second stage, the initiator is added, and in a third stage, the remainder or full amount of monomer(s) are added directly or in emulsion form in the presence of further water and, where appropriate, further dispersing assistant or other auxiliaries. It is possible for the first and second stages or second and third stages in each case also to be run in one stage while second and third stages can be run through in a gradient procedure, and in all or some stages the reaction mixture present as a dispersion is moved by an external circuit (10) which leads from and back to the polymerization vessel (2) and which comprises one or more extremely low-shear-conveying cylinder or tubular diaphragm pumps (7) and at least one heat exchanger (8), the polymerization temperature being between 40° C. and 120° C.
