NEW MATERIAL:A compound shown by formula I (R is H or methyl). EXAMPLE:N-Methoxyethoxypropylacrylamide. USE:Useful as a raw material monomer for a high polymer compound of hydrophilic-hydrophobic heat reversible type. The polymer is reversibly dissolved in water in a low-temperature range, becomes water-insoluble in a high- temperature range and is useful as a light screening material, temperature sensor, adsorbent, toy, interior, printing auxiliary and display. PREPARATION:(Meth)acrylic acid chloride is reacted with methoxyethoxypropylamine and triethylamine in a solvent such as benzene at 0-10 deg.C to give a compound shown by the formula. The vinyl compound of this invention, N-methoxyethoxypropylacrylamide and N- methoxyethoxypropylmethacrylamide are colorless liquid, soluble in solvents such as water, methyl alcohol, acetone and THF and insoluble in n-hexane and n-heptane.
