采用过硫酸盐/抗坏血酸氧化还原引发剂将丙烯腈接枝到罗望子胶上，并用红外光谱（FTIR）、X射线衍射（XRD）和扫描电子显微镜（SEM）对接枝共聚物（Tm-g-PAN）的代表性样品进行了表征。在4-12 g/L范围内，接枝率和接枝效率分别为305%和75%，接枝率和接枝效率随单体浓度、引发剂浓度和反应温度的增加而增加，随胶浓度的增加而降低。研究了接枝胶溶液的保水性、凝胶形成能力和货架期，以探索其商业化利用的可能性。© 2008 Wiley Periodicals，Inc.应用聚合物科学杂志，2009年
Acrylonitrile was grafted on to tamarind seed gum using persulfate/ascorbic acid redox initiator and a representative sample of the graft copolymer (Tm-g-PAN) was characterized using infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM). Grafting conditions were optimized where %G and %E were found to increase with the increase in the concentration of the monomer; initiator, and the reaction temperature, whereas increase in gum concentration decreased the %G in the concentration range of 4–12 g/L, The maximum % grafting (%G) and % efficiency (%E) achieved were 305 and 75%, respectively. Water/saline retention, gel forming ability, and the shelf life of the grafted gum solutions were also studied to explore the possibility of its commercial utilization. © 2008 Wiley Periodicals, Inc.
