Hyperbranched polytetritol

Figure 7.8 Synthesis of hyperbranched polytetritol (PolylOa and PolylOb) by ring-opening multibranching polymerization of 2,3-anhydroerythritol (10a) and 2,3-anhydro-DL-threitol (10b), respectively.

The resulting polytetritols were the hyperbranched glyco-conjugated polymers PolylOa and PolylOb essentially consisting of DL-threitol and erythritol units, respectively, which differed from the hyperbranched polytetritols prepared from 1,4-anhydroerythritol (6a) and 1,4-anhydro-L-threitol (6b).
