Abstract

Изобретение относится к способу производства сульфата целлюлозы, который полностью растворим в воде и имеет регулируемую вязкость раствора в водном растворе, что квалифицирует приготовленный сульфат натрий-целлюлозы (НСЦ) как вспомогательный материал с идеальной биологической совместимостью для биологических и медицинских применений, в частности он подходит для капсулирования и иммобилизации биологических объектов, например, тканей, клеток, микроорганизмов, энзимов или вирусов в микрокапсулах.
