Methyl Methacrylate → 2-Propenoic acid, 2-methyl-, butyl ester, polymer with 2-(dimethylamino)ethyl 2-methyl-2-propenoate and methyl 2-methyl-2-propenoate

Participants

Reaction Steps

In a 300 ml, three-necked flask, 12.6 g of N,N-di-methylaminoethyl methacrylate, 24.0 g of methyl methacrylate, 11.4 g of n-butyl methacrylate and 190 ml of toluene were heated to 80° C.-under stirring. A solution of 0.298 g of 2,2'-azobis-(2,4-dimethylvaleronitrile) in 10 ml of toluene was added to the reaction mixture, and the mixture is further heated for 2 hours. Then the same amount of 2,2'-azobis-(2,4-dimethylvaleronitrile) was again added to the reaction mixture, and the mixture was further heated under stirring for 2 hours. The mixture was allowed to stand at room temperature, and was poured into 1 l of n-hexane. The produced precipitate was collected on a filter, washed with two 200 ml portions of n-hexane and dried to obtain 43.7 g (yield: 91%) of the desired polymer as white solid.
