Within recent years attention has been drawn to cellulosic materials cross linked by primary valence bonds between the macromolecules because such cross linking might impart certain valuable properties to cellulose derivatives. This chemical bonding between the linear high polymer macromolecules, of which cellulose is built, changes a two- into a three-dimensional molecular lattice and causes change in one or more of the following physical properties: temperature at the softening point, tensile strength and the elongation at break, water vapour permeability and moulding characteristics as well as in solubility.
