Abstract
The present invention relates to a phosphinated poly(2,6-dimethy phenylene oxide)oligomer, specifically an unsaturated group-containing phosphinated poly(2,6-dimethy phenylene oxide)oligomer, and processes for producing the same. A thermoset produced from the unsaturated group-containing phosphinated poly(2,6-dimethy phenylene oxide)oligomers according to the present invention exhibits flame retardancy and has a low dielectric constant and dissipation factor and a high glass transition temperature.
