Claims (1)

Изобретение относится к порошкообразной, водонерастворимой, сшитой смоле, абсорбирующей водные или серозные жидкости, кровь, которую получают из 55 - 99,9 мас.% заполимеризованных, ненасыщенных, полимеризующихся мономеров, содержащих кислотные группы, нейтрализованных по меньшей мере на 25 мол. %; 0,40 мас. % заполимеризованных, ненасыщенных, сополимеризующихся с предыдущими мономеров; 0,1 - 5,0 мас.% средства сшивки и 0 - 30 мас.% водорастворимого полимера, причем весовые количества указаны в расчете на безводный полимер. Полимер отличается тем, что порошкообразную смолу покрывают 0,01 - 5 мас.% алкиленкарбоната в расчете на порошкообразную смолу, нагревают при температуре 150 - 300oС. Изобретение также относится к способу получения этого полимера, а также к его применению в изделиях санитарии в качестве пеленок и т.п., в абсорбентных конструкциях, состоящих из гидрофильных волокон и абсорбирующей смолы.The invention relates to powdered, water-insoluble, crosslinked resin, absorbing aqueous or serous fluids, blood, which is obtained from 55 - 99.9 wt.% Polymerized, unsaturated, polymerizing monomers containing acid groups, neutralized by at least 25 mol. %; 0.40 wt. % polymerized, unsaturated, copolymerizable with previous monomers; 0.1 to 5.0% by weight of the crosslinking agent and 0 to 30% by weight of the water-soluble polymer, the weight amounts being based on the anhydrous polymer. The polymer is characterized in that the powder resin is coated with 0.01 - 5 wt.% Alkylene carbonate, calculated on the powder resin, heated at a temperature of 150-300 o C. The invention also relates to a method for producing this polymer, as well as its use in sanitary articles as diapers, etc., in absorbent structures consisting of hydrophilic fibers and an absorbent resin.
