Notes:
Several linear polyesters and polyurethanes containing 2,3,4-tri-O-methylxylitol, or 2,3,4,6-tetra-O-methyl-D-glucitol, were prepared. Solution polymerization of either of the methylated derivatives with methylenebis(4-phenyl isocyanate) affords polyurethanes having molecular weights of about 30,000. Thermal polymerization of either methylated derivative with terephthaloyl chloride or mixtures of terephthaloyl chloride and sebacoyl chloride yields polyesters in the 4000-7000 molecular weight range. Films from these polyesters are brittle, with tensile strengths up to 32 kg./mm.2
