Abstract

Метод за получване на капсулиран материал в обвивки от поликарбамид, във воден разтвор на повърхностно активно вещество и предпазващ колоид, като рн на тази водна фаза се регулира между 2 и 8, характеризиращ се с това, че към водната фаза се прибавя втора фаза, несмесваща се с водната фаза, състояща се от материала, който ще се капсулира, органичен полиизоцианат и каталитично количество катализатор за фазов пренос, представляващ органична квартерна сол, несмесваща се с водната фаза се диспергира във водната фаза , рн на дисперсията се регулира между 8 и 12, при което се образува отделна поликарбамидна капсулна обвив ка около несмесващия се с водата материал. Патентните претенции са формулирани в 20 точки.
