Patent ID: 7067595

Claim:
A curable composition, comprising: a functionalized poly(arylene ether); an olefinically unsaturated monomer; about 0.2 to about 5 part by weight of a curing initiator per 100 parts by weight total of the functionalized poly(arylene ether) and the olefinically unsaturated monomer; and about 0.005 to about 1 part by weight of a curing inhibitor per 100 parts by weight total of the functionalized poly(arylene ether) and the olefinically unsaturated monomer; wherein the weight ratio of the curing initiator to the curing inhibitor is about 1.2:1 to about 50:1; and wherein the functionalized poly(arylene ether) resin is a capped poly(arylene ether) resin having the formula Q(J-K) y wherein Q is the residuum of a monohydric, dihydric, or polyhydric phenol; y is 1 to 100; J has the formula wherein R 1 and R 3 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 hydrocarbyloxy, and C 2 –C 12 halohydrocarbyloxy, wherein at least two carbon atoms separate the halogen and oxygen atoms; R 2 and R 4 are each independently selected from the group consisting of 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 hydrocarbyloxy, and C 2 –C 12 halohydrocarbyloxy 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 hydrocarbyl optionally substituted with one or two carboxylic acid groups, R 6 –R 8 are each independently hydrogen, C 1 –C 18 hydrocarbyl optionally substituted with one or two carboxylic acid groups, C 2 –C 18 hydrocarbyloxycarbonyl, nitrile, formyl, carboxylic acid, imidate, and thiocarboxylic acid; R 9 –R 13 are each independently selected from the group consisting of hydrogen, halogen, C 1 –C 12 alkyl, hydroxy, carboxylic acid, 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.
