Thermoplastic material consisting of aliphatic carbamic acid derivatives of polysaccharides and low-molecular urea derivatives as well as a process for their preparation and use of the same

Abstract From the Canadian patent

The present invention relates to evenly substituted polysaccharide derivatives having the general structure:, polysaccharide-O-R wherein polysaccharide-O represents a substituted or unsubstituted polysaccharide unit and R is a substituent of a polysaccharide-OH group having either the structure, R = -A-B-, or the structure R = -B-, wherein A is a linear polyether chain having the following structure: A = (-D-O-)n, wherein D denotes a linear aliphatic branched or unbranched chain having 2 to 12 C atoms, O represents an oxygen atom and n is a number equal to or greater than 1, and, B represents a substituted carbamic acid having the structure (see fig.I), wherein E denotes a linear or …
