CASRN: 1321-74-0

Formula: C10-H10

Synonyms/Common Names

  • Benzene, diethenyl-

Known Uses

Cross-linking monomer for copolymerization with styrene or with acrylic or methacrylic acid to produce ion-exchange resins used in home, municipal and industrial water treatment and in chemical, food and pharmaceutical processing.
