Methacrylic anhydride BiologicalActivity
| Description | Methacrylic anhydride is a typical polymerizable 1,6-diolefin. Methacrylic anhydride can form a soluble csyclopolymer by free-radical initiation. Methacrylic anhydride can spontaneously polymerize through the vinyl group and justifies the use of 2-6-di-tert-butyl4-methylphenol as an inhibitor[1][2]. |
