At the same time, dimethylphenol is an important fine chemical raw material, which is widely used in the research fields of pesticides, resins, spices, dyes, antioxidants, polymerization inhibitors, antibacterial drugs and other industries.
Reaction equation:
Polyphenylene oxide (PPO) is a high-strength engineering plastic developed in 1960s. Its chemical name is poly (2,6-dimethyl-1, 4- phenyl ether), also known as polyphenylene ether or polyphenylene ether.
1, white particles. It has good comprehensive performance, can be used in steam at 120℃, has good electrical insulation and low water absorption, but has a tendency to stress crack. Modified polyphenylene ether can eliminate stress cracking.
2. Excellent electrical insulation and water resistance, good wear resistance and electrical properties, and good dimensional stability. Its dielectric properties rank first among plastics.
