Abstract:
A thermoplastic polysaccharide-ether/carbamate/ester derivative of the general structure, wherein R is H or a substituent having a structure selected from,R=â€”Aâ€”B,â€ƒâ€ƒ(i) R=â€”Aâ€”C,â€ƒâ€ƒ(ii) R=â€”B,â€ƒâ€ƒ(iii) R=â€”C, andâ€ƒâ€ƒ(iv) R=Aâ€”Hâ€ƒâ€ƒ(v) in which A is a linear polyether chain of the following structure:A=(â€”Dâ€”Oâ€”)n in which D denotes a linear aliphatic branched or unbranched chain of 2 to 12 C atoms, O represent an oxygen atom and n is a number equal to or greater than 1, and B represents an N-substituted carbamoyl of the structure in which E denotes a linear or branched aliphatic chain of 1 to 18 carbon atoms, andC represents an alkanoyl of the structure in which F denotes a linear aliphatic, saturated or unsaturated, branched or unbranched chain of 2 to 22 C atoms, provided that said thermoplastic polysaccharide-ether/carbamate/ester derivative contains substituent R structures (iii), (iv) and at least one of (i) and (ii).
