Acetalsare a special type of ether. Many of these compounds are hydrolyzed easily, particularly in a basic medium, and their thermal stability is not very high. Upon heating, the acetals typically regenerate the aldehyde and form an ether, as shown in the following reaction for formaldehyde di...
All polymers were obtained in high yields and moderate inherent viscosity ranging from 0.25 to 0.41 dL/g. The proposed chemical structures of condensation polymers were confirmed by 1H-NMR, 13C-NMR, FTIR spectroscopies, TGA, and DSC. Thermal analysis indicated that these polymers are stable ...
