A structure of phosphorous-containing functionalized poly(arylene ether), a preparation method thereof, and a composition prepared therefrom are provided. The curable (cross-linkable) composition includes an unsaturated monomer and a phosphorous-containing functionalized poly(arylene ether) having a polymerizable group and a molecular weight between 500 and 20,000. The composition provides excellent fluidity and fast curing rate. After curing, the composition exhibits excellent low dielectric coefficient and dielectric loss, high heat resistance and flame retardancy. It is suitable for prepregs, laminated sheets for printed circuits or the like. |
