Abstract
Polyester composition characterized by a balance of physical properties more suitable for molding purposes than possible with the polyesters themselves, including blends of a polyester, poly(ethylene-co-propylene) rubber (EPR) and an ionomer of poly(ethylene-co-acrylic acid); the polyesters being selected from poly(tetramethylene terephthalate) (PBT), poly(1,4-cyclohexylenedimethylene terephthalate) (PCDT), and poly(1,4-cyclohexylenedimethylene terephthalate) (PCDT) modified with up to about 10 percent by weight of poly(oxyethylene) glycol having a molecular weight of about 500 to about 2000.
