| description | 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. |
