Abstract
1. The reactions of acetaldehyde, propionaldehyde, and butyraldehyde with poly(vinyl alcohol) in aqueous solution obey the same kinetic equations as the previously studied reaction of formaldehyde with poly(vinyl alcohol). 2. The apparent activation energy for the reaction of poly(vinyl alcohol) with acetaldehyde, propionaldehyde, and butyraldehyde (E=14.7 kcal/mole) is less than the activation energy for the reaction of poly(vinyl alcohol) with formaldehyde (E=17.4 kcal/mole); it was postulated that the observed difference is associated with the lower dipole moment of formaldehyde when compared with the other aldehydes, and with a lower energy for the reaction of this aldehyde with a proton.
