实验过程

Invented drug (acrolein:acrylic acid:trans glutaconic acid (mol)=80:15:5): 29.20 g freshly distilled acrolein, 200.22 g freshly distilled acrylic acid and 20.16 g fumaric acid were added into a three-port flask with 800 ml absolute methanol, purged with nitrogen, 10.55 g benzoyl peroxide was added, and the solution was stirred and heated to reflux under nitrogen for 75 h. The reaction solution became a yellowish viscous liquid, which was dried under vacuum at 50-100° C. for 24 hours to form to Poly (acrolein, acrylic acid, maleic acid) with an average molecular weight no less than 1000.
