Monomer: dimethylphenol. Dimethylphenol (DPM) is one of the major pollutants in the environment. Gasoline, coal tar, diesel and other energy and industrial products contain dimethylphenol, which can pollute the atmosphere when burned, and its industrial wastewater and other discharges can also pollute the atmosphere, water, and soil.
At the same time, dimethylphenol is an important fine chemical material, widely used in pesticides, resins, spices, dyes, antioxidants, polymerization blocking agents and antibacterial drugs and other research fields and a variety of industries.
Reaction equation:
Polyphenylene ether is a high-strength engineering plastic developed in the 1960s of this century, with the chemical name of poly-2,6-dimethyl-1,4-phenylene ether, abbreviated as PPO (Polyphenylene Oxide) or PPE ( Polypheylene ether), also known as polyphenylene oxide or polyphenylene ether.
1. It is white granule. Good comprehensive performance, can be used in 120 degrees steam, good electrical insulation, small water absorption, but there is a tendency to stress cracking. Modified polyphenylene ether can eliminate stress cracking.
2, has outstanding electrical insulation and excellent water resistance, good abrasion resistance and electrical properties, good dimensional stability. Its dielectric properties ranked first in plastics.
