[0074] Materials used in the following examples are described in Table 1.

[0075] Table 1

[0076]

[0077] The compositions of the following examples were prepared by compounding on a twin-screw extruder. The polymer and additives are blended together and fed through the main feeder. Strands of these compositions were cut into pellets and then dried for molding and physical testing. Table 2 shows a summary of the compounds used.

Abstract

A thermoplastic composition comprising: 25 to 95 weight percent of a poly (etherimide); 5 to 70 weight percent of a polymer different from the poly (etherimide), the polymer being partially miscible with the poly (etherimide); and 1 to 15 weight percent of a mineral filler having an average particle size of 0.1 to 10 microns; wherein the weight percentages are based on the total weight of the composition. The thermoplastic composition may be prepared by melt mixing components of the composition. Articles comprising the composition are also described.

Description

[0001] Citations to related applications [0002] This application claims priority and benefit to US Provisional Application No. 62 / 896,808, filed September 6, 2012, the contents of which are incorporated herein by reference in their entirety. Background technique [0003] Polyetherimide ("PEI") is an amorphous, transparent, high performance polymer with a glass transition temperature ("Tg") greater than 180°C. PEI further has high strength, heat resistance, and modulus as well as broad chemical resistance, and thus is widely used in various applications such as automobiles, telecommunication, aerospace, electrical / electronics, transportation, and healthcare. Compositions comprising poly(etherimide) generally exhibit high temperature resistance, high stiffness, and high strength. However, the impact properties of poly(etherimide) compositions are relatively poor. [0004] Accordingly, there remains a need in the art for poly(etherimide) compositions that can maintain the des...
