Abstract:
A thermoset composition, comprising:a capped poly(arylene ether); an alkenyl aromatic monomer; and an acryloyl monomer; wherein the capped poly(arylene ether) has the structure Q(Jâ€”K)y â€ƒwherein Q has the structure â€ƒwherein R1-R4 are each independently hydrogen, halogen, primary or secondary C1-C12 alkyl, C2-C12 alkenyl, C2-C12 alkynyl, C1-C12 aminoalkyl, C1-C12 hydroxyalkyl, phenyl, C1-C12 haloalkyl, C1-C12 aminoalkyl, C1-C12 hydrocarbonoxy, or C1-C12 halohydrocarbonoxy wherein at least two carbon atoms separate the halogen and oxygen atoms; X is hydrogen; and n is 1; y is 1; J comprises recurring units having the structure â€ƒwherein R1-R4 are as defined above; m is 1 to about 200; and K is a capping group having the structure â€ƒwherein R6-R8 are each independently selected from the group consisting of hydrogen, C1-C12 alkyl, C2-C12 alkenyl, C6-C12 aryl, C7-C18 alkyl-substituted aryl, C7-C18 aryl-substituted alkyl, C2-C12 alkoxycarbonyl, C7-C18 aryloxycarbonyl, C8-C18 -substituted aryloxycarbonyl, C8-C18 aryl-substituted alkoxycarbonyl, nitrile, formyl, imidate, and thiocarboxylate; and wherein Y is a divalent group selected from the group consisting of â€ƒwherein R14 and R15 are each independently selected from the group consisting of hydrogen and C1-C12 alkyl.
