Procedure

Control drug: (acrylic acid:acrolein (mol)=95:5): 3.25 g freshly distilled acrolein and 79.27 g freshly distilled acrylic acid were added into a three-port flask with 520 ml absolute methanol, purged with nitrogen, 4.74 g benzoyl peroxide was added, and the solution was stirred and heated to reflux under nitrogen for 50 h. The reaction solution became a yellowish viscous liquid, which was dried under vacuum at 50-100° C. for 24 hours to form poly (acrolein-acrylic acid) named A3.
