ABSTRACT:
Visually clear thermoplastic resin compositions include a polyetherimide resin, a first polyester resin and a second polyester resin, wherein from 50 to 100 mole percent of the structural units of the first polyester resin include an alicyclic hydrocarbon radical as the diol residue of the structural unit, and wherein less than 50 mole percent of the structural units of the second polyester include an alicyclic hydrocarbon radical as the diol residue of the structural unit, exhibit resistance to elevated temperature and improved impact properties.
