Abstract
In the present paper, the microwave (MW)-assisted synthesis of the alkaline N-[3-(dimethylamino)propyl]methacrylamide (4) and -acrylamide (5) monomers within minutes is described. The reaction was carried out by mixing and subsequent irradiation of 3-dimethylamino-1-propylamine (3) and (meth)acrylic acid (1/2) without addition of solvent. After polymerization, the obtained homopolymers (6/7) exhibit lower critical solution temperature (LCST) behavior in water at 35 °C only at pH = 14. The LCST-behavior can be influenced by N-oxidation of the tertiary amino group with hydrogen peroxide or by formation of a polymer-inclusion complex (6a) of 6 and β-cyclodextrin (β-CD) by addition of randomly-methylated β-CD.
