研究了超声引发下熔融状态下苯乙烯-b-(乙烯-1-丁烯)-b-苯乙烯三嵌段共聚物与马来酸酐(MAH)的官能化反应。采用酸碱滴定的方法，考察了增塑剂用量和种类、MAH含量、超声波功率、模头温度等因素对MAH接枝率的影响。用傅里叶变换红外光谱的新吸收带证实了功能化产物的存在。实验结果表明，与过氧化氢引发产物相比，超声引发产物具有较低的复粘度(η*)、较低的凝胶含量和较低的相对分子质量，说明超声可以引起链断裂，抑制交联副反应，得到凝胶含量较少、接枝率较高的官能化产物。©2013威利期刊公司J.应用。波兰姆。《科学》，2013
The functionalization of styrene-b-(ethylene-co-1-butene)-b-styrene tri-block copolymer with maleic anhydride (MAH) in melt state through ultrasound initiation was studied in this article. The effects of plasticizer content and types, MAH content, ultrasound power, and die temperature on grafting ratio of MAH were investigated by means of acid–base titration. Functionalized products were confirmed by new absorption bands in Fourier-transform infrared spectroscopy. The experimental results showed that the ultrasound initiated products had lower complex viscosity (η*), lower gel content as well as lower molecular weight than peroxide initiated products, indicating that the ultrasound could cause chain scission and suppress the crosslinking side reaction to gain functionalized products, which have less gel content and high grafting ratio. © 2013 Wiley Periodicals, Inc.
