pH对丙烯酸-丁烯醛共聚物与明胶相互作用的影响

Effect of pH on Interaction between Poly(Acrylic acid-Crotonaldehyde) and Gelatin

以明胶为皮胶原的模型化合物,研究了pH对丙烯酸-丁烯醛共聚物与明胶相互作用的影响。实验结果表明,丙烯酸-丁烯醛共聚物与明胶的相互作用大小与介质的pH值有关,在pH=4.5附近,相互作用最强。

The interaction between poly(acrylic acid-crotonaldehyde) and gelatin, in which gelatin was used as the model of collagen, was studied using FT-IR and precipitate method. The results show that the interaction between poly(acrylic acid-crotonaldehyde) and gelatin is relative to pH and at pH=4.5 the interaction is the strongest.
