New polymers with functionalized dihydropyrimidones were synthesized.The methacryloyl chloride was first reacted with 4-hydroxybenzaldehyde,and the affording aldehyde was upon the one-pot Biginelli reaction to afford new monomers with dihydropyrimidone as pending groups (M1,M2).Two new monomers were polymerized via radical polymerization to afford interesting color changeable polymers in different pH.The polymers were characterized by ~1H-NMR and IR methods.The color changeable properties were also investigated.

The methacryloyl chloride was first reacted with 4-hydroxybenzaldehyde, and the affording aldehyde was upon the one-pot Biginelli reaction to afford new monomers with dihydropyrimidone as pending groups (M1, M2). Two new individuals were polymerized via radical polymerization to afford interesting color changeable polymers in different pH. these polymers were characterized by ~ 1H-NMR and IR methods. color changeable properties were also investigated.
