Patent ID: 6905637

Claim:
A thermoset composition, comprising: a functionalized poly(arylene ether); an alkenyl aromatic monomer; an acryloyl monomer; and a conductive agent; wherein the functionalized poly(arylene ether) is a capped poly(arylene ether) having the structure Q ( J−K ) y wherein Q is the residuum of a monohydric, dihydric, or polyhydric phenol; y is 1 to 100; J consists of recurring units having the structure wherein R 1 -R 4 are each independently selected from the group consisting of hydrogen, halogen, primary or secondary C 1 -C 12 alkyl, C 2 -C 12 alkenyl, C 2 -C 12 alkynyl, C 1 -C 12 aminoalkyl, C 1 -C 12 hydroxyalkyl, phenyl, C 1 -C 12 haloalkyl, C 1 -C 12 hydrocarbonoxy, and C 2 -C 12 halohydrocarbonoxy wherein at least two carbon atoms separate the halogen and oxygen atoms; m is 1 to about 200; and K is a capping group selected from the group consisting of wherein R 5 is C 1 -C 12 alkyl; R 6 -R 8 are each independently selected from the group consisting of hydrogen, C 1 -C 12 alkyl, C 2 -C 12 alkenyl, C 6 -C 18 aryl, C 7 -C 18 alkyl-substituted aryl, C 7 -C 18 aryl-substituted alkyl, C 2 -C 12 alkoxycarbonyl, C 7 -C 18 aryloxycarbonyl, C 8 -C 18 alkyl-substituted aryloxycarbonyl, C 8 -C 18 aryl-substituted alkoxycarbonyl, nitrile, formyl, carboxylate, imidate, and thiocarboxylate; R 9 -R 13 are each independently selected from the group consisting of hydrogen, halogen, C 1 -C 12 alkyl, hydroxy, and amino; and wherein Y is a divalent group selected from the group consisting of wherein R 14 and R 15 are each independently selected from the group consisting of hydrogen and C 1 -C 12 alkyl.
