Abstract

A composition includes specific amounts of a poly(phenylene ether)-polysiloxane block copolymer reaction product and an impact modifier. The poly(phenylene ether)-polysiloxane block copolymer reaction product includes a poly(phenylene ether) and a poly(phenylene ether)-polysiloxane block copolymer. The composition exhibits a desirable balance of impact strength, heat resistance, and flame retardancy while minimizing or excluding flame retardant additives such as organophosphate esters and halogenated flame retardants.

Description

Background technique [0001] Poly(phenylene ether)s are a class of plastics known to have excellent water resistance, dimensional stability, and inherent flame retardancy. Various properties such as strength, hardness, chemical resistance and heat resistance can be adjusted by blending it with various other plastics to meet a variety of consumer products, such as plumbing fixtures, electrical boxes, automotive components, and wire and cable insulation needs. [0002] Significant flame retardancy is required for some applications of poly(phenylene ether)-based resins. Examples include applications in the construction, transportation, electronics, and solar power industries. Poly(phenylene ether) is an inherent flame retardant, but it is often blended with an impact modifier which, while improving the processing and mechanical properties of the resulting composition, reduces its Flammability. Therefore, there is often a need for flame retardant additives for blends of poly(ph...
