摘要:
A varnish composition for producing an electrically insulative thermoset coating is provided. The varnish composition includes poly(phenylene ether) having at least one end group having aliphatic unsaturation and a reactive solvent. When cured, the poly(phenylene ether) and reactive solvent form an electrically insulative thermoset.

The invention relates to a composite formulation comprising a specific mediator additive component (A) of relatively high molecular weight, a filler component (B) and a binder component (C). The composite formulation can be cured to a composite which is especially suitable for the production of moldings.
摘要:
A curable composition includes an alkyl styrene and a low molecular weight, bifunctional poly(arylene ether). The composition can be prepared and processed at substantially lower temperatures than prior art poly(arylene ether) thermosets. After curing, the composition exhibits an improved balance of heat resistance, impact strength, and dielectric properties, making it particularly suitable for the fabrication of electronic components.
