[0002] This application claims priority and benefit to European Patent Application No. 20211298.3, filed on 2 December 2020, the contents of which are incorporated herein by reference in their entirety. Background Technology

[0003] Thermoplastic polymers, including polyetherimide and poly(aryl ether sulfone), are used in the manufacture of articles and components for a wide range of applications, from automotive parts to electronic devices. Due to their beneficial properties such as transparency and impact resistance, polyetherimide and poly(aryl ether sulfone) have also been used in optical applications, including as sensor lenses, optical interconnects, transceivers, light guides, camera lenses, eyeglasses and safety glass lenses, lighting lenses (such as lamps), flashlight and lantern lenses, and headlight lenses and covers for motor vehicles. Because many optical products are used in high-temperature environments or must be processed under harsh conditions, it is desirable for materials to withstand elevated temperatures without deformation or discoloration, and to maintain good optical performance even when processed using standard mass production processes. To date, many optical lenses have been made of glass because polymer materials cannot provide the necessary dimensional stability, particularly for single-mode fiber optic connectors.

[0004] Therefore, there is a continued need in the art for improved compositions particularly suitable for optical applications. Compositions that provide a low coefficient of thermal expansion and high infrared transmittance while maintaining other good physical properties such as tensile properties, flexural properties, and impact strength would be particularly advantageous. Summary of the Invention

[0005] The composition comprises 20 to 75 wt% of polyetherimide or poly(arylene ether sulfone); 5 to 35 wt% of a second polymer comprising a polycarbonate-ester copolymer or a polyester; and 20 to 60 wt% of boehmite, preferably wherein the boehmite has an average particle size of less than 1 micrometer as determined by laser scattering; wherein the weight percentages are based on the total weight of the composition.

[0006] Methods for preparing the composition include melt-mixing the components of the composition and optionally extruding the composition.

[0007] Articles comprising the composition were also disclosed.

[0008] The above and other features are illustrated by the following detailed description. Detailed Implementation

[0009] The inventors have unexpectedly discovered that compositions comprising polyetherimide or poly(aryl ether sulfone); a second polymer comprising a polycarbonate-ester copolymer or a polyester; and specific inorganic fillers. In particular, specific amounts of boehmite can provide molded compositions exhibiting a low coefficient of thermal expansion (CTE), high infrared (IR) transmittance, and good processability. Not wishing to be bound by theory, it is believed that the addition of a second polymer can help adjust the refractive index of the composition and impart improved flowability for easier processing. Therefore, the compositions described herein are particularly suitable for a wide variety of articles, especially those for optical applications.
