FIELD: medicine. ^ SUBSTANCE: invention refers to polymers producing hydrogel and absorbing aqueous liquids, based on acid group carrying polymers produced by polymerisation of monoethylenoid-nonsaturated carboxylic acids with 3-25 carbon atoms, containing ?-tocopherol as stabilising additive. Purpose of present invention is production of superabsorber with application as stabilising additive of native monomers of health-hazardless substance, as well as reduced duration of induction and production of superabsorber which does not have undesired colouring. Purpose in view is provided by the fact that as stabilising additive monoethylenoid-nonsaturated carboxylic acids with 3-25 carbon atoms, ?-tocopherol is used; therefore duration of an induction of polymerisation is reduced, provided production of polymer which acts as superabsorber, having required colouring. ^ EFFECT: present invention concerns method of production of such polymers, their application for aqueous liquids absorption, specifically in hygienic products. ^ 10 cl, 2 ex |
