Novel stereoregular carbohydrate-derived [m,n]-polyurethanes have been prepared using D-mannitol (1) as renewable and low cost starting material. The key comonomer, 1,6-di-O-phenylcarbonyl-2,3,4,5-tetra-O-methyl-D-mannitol, was polymerized with a diamine synthesized from 1 or with alkylenediamines. These polymerizations led, respectively, to a [6,6]-polyurethane entirely based on a carbohydrate or to [m,n]-polyurethanes constituted by a poly-O-methyl substituted unit alternating with a polymethylene chain. Thermal studies (DSC) indicated that polymers are amorphous materials with Tg values dependent on the structure and chain length of the diamine constituent.
