Acetone → 2-Methylprop-2-enoic acid--prop-2-enimidic acid (1/1)

Participants

Reaction Steps

After 20 g of the obtained prepolymers were dissolved in 62 g of dimethyl sulfoxide, 6.71 g of glycidyl methacrylate, 504 mg of N,N-dimethyldodecylamine (catalyst), and 62.4 mg of hydroquinone (polymerization inhibitor) were added. The obtained solution was allowed to react for 7 hours at 140° C. in a nitrogen atmosphere. Acetone was added to the resultant solution to precipitate a polymer. The polymer was sufficiently washed to obtain 23.4 g of terminal methacrylate acrylamide macromonomer (weight average molecular weight: 1,400). It was confirmed that a polymerizable group was introduced into the terminal because H1-NMR(D20) 6.12, 5.70 ppm methacryloyl group olefin peak, and the acid value (0.057meq/g) decreased.
