Claim 2:
3. The ultraviolet light-curable coating composition of claim 1, wherein the ultraviolet light-curable poly(polyphenylene ether) oligomer comprises
at least one allyl, vinyl, or (meth)acrylate terminal group;
a poly(polyphenylene ether) block of the formula, , wherein
each occurrence of Z1 is independently halogen, unsubstituted or substituted C1-12 primary or secondary hydrocarbyl, C1-12 hydrocarbylthio, C1-12 hydrocarbyloxy, or C2-C12 halohydrocarbyloxy wherein at least two carbon atoms separate the halogen and oxygen atoms, and
each occurrence of Z2 is independently hydrogen, halogen, unsubstituted or substituted C1-12 primary or secondary hydrocarbyl, C1-12 hydrocarbylthio, C1-12 hydrocarbyloxy, or C2-12 halohydrocarbyloxy wherein at least two carbon atoms separate the halogen and oxygen atoms; and a polysiloxane block comprising repeating units of the formula
a polysiloxane block comprising repeating units having the structure, , wherein
each occurrence of R3 is independently C1-12 hydrocarbyl or C1-12 halohydrocarbyl, and the polysiloxane block further comprises a terminal unit of formula (6), wherein
Y is hydrogen, halogen, C1-12 hydrocarbyl, or C1-12 hydrocarbyloxy, and
each occurrence of R3 is independently hydrogen, C1-12 hydrocarbyl, or C1-12 halohydrocarbyl.
