Structure and properties of oxycelluloses before and after beating using X-ray diffraction

Popis výsledku v původním jazyce

Oxidized celluloses belong to a very interesting class of cellulose derivatives with unique chemical and mechanical influence on supermolecular structure of cellulose significantly different from those of unmodified cellulose. Oxidative-hydrolysis process taking place during oxycellulose preparation has a qualitative influence upon crystalline domains of cellulose. Primary cellulose I is changed during oxycellulose preparation to more amphoteric polymorph cellulose II being change further by beating topolymorphs II and IVII in the case of intensively oxidized cellulose (15 % and 19 % of COOH groups) and to polymorph IVI for carefully oxidation of bleached linters (3.5 % of COOH groups). In contrast to oxycellulose, intensively fibrillation beating ofnative cellulose leads only to increase of amount the crystalline domains in cellulose.
