Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an emulsion homopolymer and copolymer having excellent performances and characteristics by which the method can be practiced on an industrial scale in a short reactional time and application can be made to various monomers, and an apparatus used therefor. SOLUTION: This method for producing an emulsion homopolymer and copolymer is to carry out the (co)polymerization from a specific kind of monomer(s) so that the monomer(s) may occupy at least 85wt.% of the (co)polymer. The method comprises (a) a step for adding water or, as necessary, a dispersion assistant, a seed and a part of the monomer(s), (b) a step for adding an initiator, (c) a step for adding the residual total monomer(s) directly or in the form of an emulsion and further, as necessary, in the presence of another dispersion assistant or carrying out the steps (a) and (b) or the steps (b) and (c) as a single step, keeping the reactional mixture in a state of its dispersion and installing one or more low-shearing pumps and one or more essentially laminar flow type heat exchangers in any steps or each step, starting the reactional mixture from a reactor, making the reactional mixture flow through an external circuit returning to the reactor and polymerizing the reactional mixture at 40-120 deg.C temperature.

Abstract: The invention relates to a method for producing polymer dispersions of at least one of the monomers that can be polymerized from the following groups: alkyl(meth)acrylates, vinyl esters of carboxylic acids comprising 1-20 C atoms, vinyl aromatic compounds, nitriles, vinyl halides, vinyl ethers, hydrocarbons comprising 2-8 C atoms and monomers containing hydroxyl groups, using emulsion polymerization technology at a polymerization temperature of at least 40 DEG C in the presence of a radical polymerization initiator. The polymer which is produced from at least 85 wt. % of one or several of said monomers is produced in the following way: in a first stage, water, which acts as an inert solvent during the reaction, optionally a dispersant, seed particles and optionally a first sub-quantity of the monomer(s) are added. In a second stage, the initiator is added. In a third stage, the remaining quantity or the total quantity of the monomer(s) is added directly or in the form of an emulsion in the presence of additional water. The first and second stages, or the second and third stages respectively can be carried out as a single-stage, whereas the second and third stages can also be carried out in a gradient operation. In individual or all stages of the reaction mixture that is present as a dispersion, said mixture is displaced by an external circuit (10) that leads from and returns to the polymerization container (2). The circuit comprises one or more hose or cylinder diaphragm pumps (7), which transport the product with a low shear rate and at least one heat exchanger (8), whereby the polymerization temperature lies between 40 DEG C and 120 DEG C.

Abstract: 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.
