Abstract

Настоящее изобретение, в целом, относится к способу получения водоабсорбирующих полимерных частиц, включающему технологические стадии (i) получения водного раствора мономера, содержащего по меньшей мере один частично нейтрализованный, моноэтиленненасыщенный мономер, содержащий группы карбоновой кислоты (α1), и по меньшей мере один сшивающий агент (α3); (ii) необязательного добавления мелких частиц водоабсорбирующего полимера к водному раствору мономера; (iii) добавления инициатора полимеризации или по меньшей мере одного компонента системы инициатора полимеризации к водному раствору мономера; (iv) необязательного уменьшения содержания кислорода в водном растворе мономера; (v) загрузки водного раствора мономера в реактор полимеризации; (vi) полимеризации мономеров в водном растворе мономера в реакторе полимеризации; (vii) выгрузки полимерного геля из реактора полимеризации и необязательного дробления полимерного геля; (viii) высушивания полимерного геля; (ix) измельчения высушенного полимерного геля с получением водоабсорбирующих полимерных частиц; (х) сортировки измельченных водоабсорбирующих полимерных частиц с помощью сортировочного устройства, содержащего решетку; и (xi) необязательной обработки поверхности измельченных и отсортированных по размеру водоабсорбирующих полимерных частиц; где на технологической стадии (х) решетка вибрирует с первой частотой; и где решетка вибрирует с дополнительной частотой, которая меньше первой частоты, или наклонена к горизонтальной плоскости под углом, составляющим от 5 до 25°, или оба вышеуказанных варианта.
