摘要： Compositions formed from a blend of polyetherimide, siloxane/bisphenol-A polyester/polycarbonate copolymer, polycyclohexylenedimethylene terephthalate, polycarbonate/siloxane copolymer, and styrene-ethylene-butadiene-styrene are disclosed that provide superior performance in terms of notched Izod impact, glass transition temperature (Tg), strength after aging, ability to withstand secondary processing conditions, and in other respects. Such compositions exceed critical-to-quality requirements for use in manufacturing components for electronic communication devices.

摘要： Thermoplastic compositions include: from about 62 wt % to about 99 wt % poly(methyl methacrylate) (PMMA) or copolymers thereof; and from about 1 wt % to about 38 wt % of a poly(carbonate-siloxane) copolymer having a siloxane content of from about 25 wt % to about 45 wt %. The compositions are scratch resistant. Scratch resistance may be determined as comprising a scratch depth of less than 20 micron (μm) as measured in accordance with the Erichsen scratch hardness test at a force of 4 Newton (N). Articles including the thermoplastic composition are also described.

摘要： Disclosed is a quantum dot composition comprising: a polycarbonate resin, a polycarbonate copolymer resin, or a combination thereof; a quantum dot concentrate including a plurality of nanoparticle quantum dots and an acrylic polymer, a methacrylic polymer, or a combination thereof; and a compatibilizer for promoting dispersion of the nanoparticle quantum dots in the quantum dot composition. The compatibilizer includes a transesterification catalyst, a physical compatibilizer, a plurality of semiconductor nanopartides passivated with a metal oxide, or a combination thereof. Further disclosed is a method for making a quantum dot composition, the method including: forming a quantum dot concentrate by combining a plurality of nanoparticle quantum dots with an acrylic polymer, a methacrylic polymer or a combination thereof; and combining the quantum dot concentrate with a compatibilizer and a polycarbonate resin, a polycarbonate copolymer resin, or a combination thereof.
