Abstract: A copolymer includes a repeating unit corresponding to polyether sulfone and a repeating unit corresponding to vinyl monomer. The repeating unit corresponding to polyether sulfone has a repeating number of 200 to 450, and the repeating unit corresponding to vinyl monomer has a repeating number of 20 to 100. The copolymer can be blended with another polymer such as polyphenylene sulfide to form a blend.
