Claim 0:
1. A curable composition comprising:
20 to 40 weight percent of a functionalized phenylene ether oligomer having an intrinsic viscosity of 0.03 to 0.13 deciliter per gram, measured at 25° C. in chloroform using an Ubbelohde viscometer;
60 to 80 weight percent of a reactive diluent, wherein the reactive diluent is a (meth)acrylate-containing monomer; and
a photoinitiator;
wherein weight percent is based on the total weight of the phenylene ether oligomer and the reactive diluent; and
wherein the functionalized phenylene ether oligomer has the structure, wherein
Q1 and Q2 each independently comprise halogen, unsubstituted or substituted C1-12 primary or secondary hydrocarbyl, C1-12 hydrocarbylthio, C1-12 hydrocarbyloxy, and C2-12 halohydrocarbyloxy wherein at least two carbon atoms separate the halogen and oxygen atoms;
Q3 and Q4 each independently comprise hydrogen, halogen, unsubstituted or substituted C1-12 primary or secondary hydrocarbyl, C1-12 hydrocarbylthio, C1-12 hydrocarbyloxy, and C2-12 halohydrocarbyloxy wherein at least two carbon atoms separate the halogen and oxygen atoms;
Z is independently at each occurrence a (meth)acrylate group, a vinyl benzene group, an allyl group, or a maleimide group; and
L is of the structure, wherein
R3, R4, R5, and R6 each independently comprise hydrogen, halogen, unsubstituted or substituted C1-12 primary or secondary hydrocarbyl, C1-12 hydrocarbylthio, C1-12 hydrocarbyloxy, and C2-12 halohydrocarbyloxy wherein at least two carbon atoms separate the halogen and oxygen atoms;
z is 0 or 1; and
Y has a structure, wherein
R7 is independently at each occurrence hydrogen and C1-12 hydrocarbyl;
R8 and R9 are independently at each occurrence hydrogen, C1-12 hydrocarbyl, and C1-6 hydrocarbylene wherein R8 and R9 collectively form a C4-12 alkylene group;
R10 is independently at each occurrence a C1-6 hydrocarbylene group;
R11 is independently at each occurrence a hydrogen, C1-12 hydrocarbyl or C1-12 halohydrocarbyl; and
n is 5 to 50; and

x and y are independently 0 to 30, provided that the sum of x and y is at least 2.
