丙烯酸

From the influnce of pH change in water on the copolymerization, the copolymerization mechanism was provided. The copolymerization mechanism is that there is hydrogen bond, which can enhance the copolymerization, between acrylic acid and crotonaldehyde at low pH and there is"Charge Transfer Complex", which gives the more crotonaldehyde in P (acrylic acid-crotonaldehyde), between acrylic acid and crotonaldehyde at high pH.

根据共聚合反应介质pH值变化对丙烯酸-丁烯醛共聚合反应的影响，提出了丙烯酸-丁烯醛共聚合反应机理，即在低pH值时，丙烯酸、丁烯醛之间可形成氢键，从而使共聚合体系具有较高的聚合反应速率和转化率；在较高pH值时，丙烯酸、丁烯醛之间则有电荷转移络合物形成，从而使共聚物中含有更多的丁烯醛链段。
