Abstract:
A curable poly(phenylene ether) composition which comprises:(a) a poly(phenylene ether) containing hydroxyl endgroups that have been capped with a compound containing ethylenic unsaturation; wherein the poly(phenylene ether) has the structure Qâ€”(Jâ€”K)y wherein Q has the structure â€ƒwherein X is hydrogen; R1-4 are independently hydrogen, C1-100 alkyl, C1-100 aryl, or C1-100 mixed alkyl-aryl hydrocarbon; and n is 1; wherein J has the structure â€ƒwherein R5-8 are independently hydrogen, unsubstituted or substituted alkyl, unsubstituted or substituted alkenyl, unsubstituted or substituted alkynoyl, unsubstituted or substituted aryl, or unsubstituted or substituted mixed alkyl-aryl hydrocarbons, wherein substituents may be selected from the group consisting of carboxylic acid, aldehyde, alcohol, and amino; and m is 1-200; wherein K has the structure â€ƒwherein Z is â€ƒand wherein each of R9-11 is independently hydrogen, C1-100 alkyl, C1-100 aryl, or C1-100 mixed alkyl-aryl; and wherein y is 1; wherein at least 10% of the hydroxyl groups have been capped; and(b) a curable unsaturated monomer comprising one or more of a monofunctional styrenic compound, a polyfunctional styrenic compound, a monofunctional acrylate compound, a polyfunctional acrylate compound, or a polyfunctional acrylamide compound.
