Abstract
An oligomer (2,6-dimethylphenylene ether) is provided. Its structure is shown as follows: which comprises separately independent hydrogen; alkyl or phenyl; separately independent —NR—, —CO—, —SO—, —CS—, —SO2—, —CH2—, —O—, null, —C(CH3)2—, or and a hydrogen, The features of the cured products include a high glass-transition temperature, a low dielectric feature, preferred thermal stability, and good flame retardancy. The present invention effectively controls the number-average molecular weight of the product to obtain excellent organic solubility.
