The present invention relates to a polymer composition comprising a thermoplastic polyester and a propylene-based elastomer, wherein the propylene-based elastomer comprises propylene-derived units and 5 to 30 wt % of &#x3b1;-olefin-derived units, and has a melting temperature of less than 120&#xb0; C. and a heat of fusion of less than 75 J/g.

Polyester compositions, and process for making articles therefrom

The present invention is related to a propylene-based injection molded composition made from a polymer blend comprising from 45 to 85 wt % of a polymer blend modifier having a weight average molecular weight of 10,000 to 100,000 g/mole and from 15 to 55 wt % of a propylene-based elastomer having a weight average molecular weight of from 100,000 to 300,000 g/mole, where the weight percent of the polymer blend modifier and the propylene-based elastomer are based on the total weight of the polymer blend. The polymer blend modifier comprises a first propylene-based polymer and a second propylene-based polymer, where the first and second propylene-based polymers are different and are individually selected from a homopolymer of propylene or a copolymer of propylene and ethylene or a Cto Calpha-olefin.
