α-(氨甲基)丙烯酸乙酯是一种在α-位带有共轭亚乙烯基团的β-氨基酸酯，它被自由基聚合。发现聚合反应涉及聚合物的氨基和单体的酯基之间的随后的酯-酰胺交换反应，得到11-15%的含丙烯酰胺单元。所得聚合物在水介质中具有pH/温度响应性。
Ethyl alpha-(aminomethyl) acrylate, a beta-amino acid ester carrying a conjugated vinylidene group at the alpha-position, was radically polymerized. The polymerization was found to involve subsequent ester-amide exchange reaction between the amino pendants of the polymer and an ester group of the monomer, affording acryl-amide-bearing units in 11-15% contents. The obtained polymer exhibited pH/temperature responsiveness in aqueous media.
