Abstract: This disclosure relates to a curable composition that includes at least first, second, and third polymers. The first polymer includes a first monomer unit and a second monomer unit different from the first monomer unit, in which the first monomer unit has the structure of formula (I) defined in the Specification and the second monomer unit has the structure of formula (II) defined in the Specification. The second polymer includes at least about 60 wt % of a styrene monomer unit; and the third polymer includes at most about 60 wt % of a styrene monomer unit. This disclosure also relates to using the composition to form a free-standing film, a laminate, a prepreg, and/or a printed circuit board.

Abstract: A resin composition for use in making pre-pregs and structural laminates contains a functionalized poly(phenylene ether) having the structure below: a radical initiator, the radical initiator being from about 0.1% to about 0.5% by weight of the composition; an unsaturated monomer; and a flame retardant comprising the compound 1,1?(ethane-1,2-diyl)bis[pentabromobenzene]. In the above structure, Y, m and n are defined in the Specification.
