The present invention relates to a phosphorus-based poly(2,6-dimethylphenyl ether) oligomer and a process for the preparation thereof. Wherein, the unsaturated group-containing double bond phosphorus-based poly(2,6-dimethylphenyl ether) oligomer can be further used for preparing a flame-retardant heat-curable material, which has flame retardancy and low dielectric property. Constant, low dielectric loss and high glass transition temperature. |
