Description

[Technical Field]

[0001] The present invention relates to compositions, methods for their preparation, and articles made therefrom. [Background technology]

[0002] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims priority to and the benefit of European Patent Application No. 20211298.3, filed December 2, 2020, the entire contents of which are incorporated herein by reference.

[0003] Thermoplastic polymers (including polyetherimides and poly(arylene ether sulfones)) are useful for manufacturing articles and components for a wide range of applications, from automotive parts to electronic devices. Because of their beneficial properties, such as transparency and impact resistance, polyetherimides and poly(arylene ether sulfones) are also used in optical applications, such as sensor lenses, optical interconnectors, transceivers, light guides, camera lenses, eyeglass and safety eyewear lenses, lighting lenses (e.g., illuminators, flashlights, and lantern lenses), and automotive headlight lenses and covers. Because many optical articles are used in high-temperature environments or must be processed under harsh conditions, materials that can withstand high temperatures without deformation or discoloration and retain good optical properties when processed using conventional molding processes are desirable. To date, polymeric materials have not provided the necessary dimensional stability, particularly for use in single-mode fiber optic connectors, so most optical lenses are made from glass. Summary of the Invention [Problem to be solved by the invention]

[0004] Thus, there is a need in the art for improved compositions that are particularly well suited for optical applications. It would be particularly useful to provide compositions that have a low coefficient of thermal expansion, high infrared transmittance, and yet retain good other physical properties (tensile properties, flexural properties, impact strength, etc.). [Means for solving the problem]

[0005] A composition comprising 20 to 75 weight percent of a polyetherimide or poly(arylene ether sulfone), 5 to 35 weight percent of a second polymer, and 20 to 60 weight percent of boehmite, wherein the second polymer comprises a polycarbonate-ester copolymer or a polyester, and the boehmite desirably has an average particle size of less than 1 micrometer (μm) as measured using laser light scattering, wherein the weight percents are based on the total weight of the composition.

[0006] A method for making the composition includes melt mixing the components of the composition and, optionally, extruding the composition.

[0007] Articles comprising the compositions are also disclosed.

[0008] These and other features are illustrated by way of example in the detailed description that follows. DETAILED DESCRIPTION OF THE INVENTION

[0009] The inventors of the present invention have unexpectedly discovered that compositions comprising a polyetherimide or poly(arylene ether sulfone), a second polymer comprising a polycarbonate-ester copolymer or polyester, and a specific inorganic filler exhibit a desirable combination of properties. Specifically, a specific amount of boehmite can result in molding compositions exhibiting low coefficients of thermal expansion (CTE), high infrared (IR) transmittance, and good processability. Without wishing to be bound by theory, it is believed that the addition of the second polymer facilitates tuning of the refractive index of the composition and also improves flowability and ease of processing. Therefore, the compositions described herein are believed to be particularly well suited for a variety of articles, particularly those used in optical applications.

[0010] One aspect of the present disclosure is a composition comprising a polyetherimide or a poly(arylene ether sulfone).

This mixture can be fed from a hopper into the throat of a twin-screw extruder. Alternatively, at least one of the components can be incorporated into the composition by feeding it directly into the extruder at the throat or through a downstream sidestuffer, or by blending it with the desired polymer to form a masterbatch and feeding this into the extruder. The extruder is generally operated at a temperature higher than that required to render the composition fluid. The extrudate can be quenched in a water bath and pelletized. The pellets thus produced can be up to one-quarter inch (i.e., 0.635 cm) in length, as desired. Such pellets can be used for subsequent molding, shaping, or forming, for example, compression molding, injection molding, and the like.
