Yield:79-39-0 85%
Reaction Conditions:
with ammonia at 0 - 5; for 1 h;Green chemistry;
Steps:
Synthesis of monomer was carried out by mixing 0.1 mol (10 ml)of ammonia with 1 g of clay catalyst Maghnite-H+ 0.25M (10%), after that, we added 0.1 mol (15 ml) of methacrylic anhydride (with a molar ratio of 1:1 of methacrylic anhydride to ammonia) in bulk; the reaction mixture was cooled to 0-5 °C using an ice bath during 1 h. After that, we filtered the solution recover the product (Scheme1). The product obtained was a white powder which when recrystallized in a methanol-diethyl ether mixture. Yield: 85%.The anionic polymerization of MAM was carried out in sealed tubes. Each tube contains a mixture of 1 g of MAM, 10 ml of tetrahydrofuran THF and (0.15 g) 15% of Maghnite-Na. The mixtures werekept in an ice bath at 0 °C and stirred with a magnetic stirrer under dry nitrogen for 2 h 30 min. The resulting polymer was precipitated in methanol, washed for several times, dried at 40 °C in vacuum and weighed (yield 55%).
