FIELD: polymer production. SUBSTANCE: invention relates to unsaturated compound polymerization technique, in particular, that of acrylic acid polymerization, and may be used for producing iron-containing polyacrylic acid utilized in medicine and engineering. Installation includes polymerization reactor with feeding and emptying pipes and, connected with reactor feeding pipe, ingredient transportation means, and acrylic acid and potassium persulfate batchboxes. According to invention, installation is also provided with, disposed before reactor, tank to dissolve MohrÆs salt with solution feed control means and, disposed after reactor, tank to control polymer solution concentration, reactor being connected through feeding pipe and solution feed control means with tank to dissolve MohrÆs salt and, through emptying pipe, with polymer concentration control tank. In a preferred embodiment of invention, installation also contains impurity sorption and sorbent regeneration module installed after polymer concentration control tank and, connected with it, transportation means. EFFECT: improved polymer quality. 2 cl, 5 dwgi
