Procedure

The title microparticle was synthesized according to the method described in Example I(c) but using glycolide (2.586 mole, 300 g), anhydrous malic acid (0.172 mole, 23 g), and stannous octoate (0.2 M in toluene, 862 ml, 0.172 m mole). Differential Scanning Calorimetry was used to determine the polymer melting temperature (Tm=206° C.).

Workup

  1. customThe title microparticle was synthesized
  2. customthe polymer melting temperature (Tm=206° C.)
