Process for making polyetheresters with high aromatic ester content |
| abstract |
A two-step process for making polyetherester resins is disclosed. A low molecular weight polyol reacts with an aromatic dicarboxylic acid in step one to produce a polyester intermediate. In step two, the polyester intermediate reacts with an anhydride or an aliphatic dicarboxylic acid in the presence of an insertion catalyst to produce a polyetherester resin that contains greater than about 10 wt. % of recurring units derived from the aromatic dicarboxylic acid. The polyetheresters are useful for making thermoset resins with excellent mechanical properties and chemical resistance. |
