Abstract: NEW MATERIAL:A compound expressed by formula I (R1 represents H or methyl; R2 represents lower alkyl). EXAMPLE:N-Methoxypropylacrylamide. USE:Useful as a raw material monomer for hydrophilic-hydrophobic thermoreversible high polymers. PREPARATION:For example, acryloyl chloride or methacryloyl chloride expressed by formula II is reacted with a 3-alkoxypropylamine expressed by formula III and triethylamine expressed by formula IV in a solvent preferably at 0-10 deg.C to obtain the compound expressed by formula I. A polymer prepared from the compound expressed by formula I is a thermoreversible derivative, which dissolves in water at low temperatures, reversibly becomes insoluble in water at high temperatures and is useable for a light shield, thermosensor, adsorbent, toy, etc.
