Abstract
Сущность изобретения: в формовочном материале и материал для формования волокна, которые содержат соответственно целлюлозу, третичный аминоксид, осадитель и стабилизатор, предусмотрено использование одного или нескольких стабилизаторов, которые совместно имеют щелочное и противоокислительное действие, при условии, что в стабилизаторе, имеющем щелочное действие, отсутствует фосфат. Формовочный материал и материал для формования волокна, соответствующие изобретению, термически стабилизированы против выхода из-под контроля реакции разложения. Также в значительной степени предотвращено расщепление целлюлозы и аминоксида.
