Abstract

Изобретение относится к способу получения водорастворимых или водонабухающих полимеризатов из акриловой кислоты и/или производных акриловой кислоты с низким содержанием остаточных мономеров. Способ характеризуется тем, что азотсодержащее соединение добавляют к раствору мономера, подлежащего полимеризации, и тем, что полимеризат подвергают последующему нагреву при температурах от 120 до 240°C. Полимеризаты, полученные согласно этому способу, пригодны, наряду с прочим, для использования в качестве коагулянтов, диспергаторов и абсорберов.Международная заявка была опубликована вместе с отчетом о международном поиске.
