ABSTRACT = {A batch of linear [m,n]-type sugar-based polyureas was synthesized by polyaddition reaction in solution from 
hexamethylene diisocyanate or 4,4’-methylene-bis(phenyl isocyanate) with the acyclic 2,3,4-tri-O-methyl-1,5-
diamino-alditols having L-<i>arabino</i>, or <i>xylo</i> confi guration or the bicyclic 1,6-diamino-1,6-dideoxy-2,4:3,5-diO-methylene-D-glucitol. The polymers were obtained in good yields and fair molecular weights. All these 
polyureas were semicrystalline materials showing well-defi ned melting transition within the 86−171°C range, 
with T<sub>g</sub>
s being dependent on the aliphatic or aromatic nature of the diisocyanate used, and on the cyclic or 
acyclic chemical structure of the sugar moiety. They were found to be stable up to around 240°C, decomposing 
at higher temperatures through a one- or two-stage mechanism.},
