摘要

采用共辐射法制备了黄原胶-N-乙烯基吡咯烷酮接枝共聚物（XG-g-NVP）。研究表明在黄原胶浓度及XG/NVP质量比一定的情况下，接枝率随吸收剂量的增加而增加，并逐步达到平衡；在吸收剂量和质量比一定时，接枝率在浓度为10 g/L达到最大；在吸收剂量和黄原胶浓度一定时，接枝率在质量比为10: 1达到最大值。红外光谱研究表明接枝反应发生在NVP乙烯基部位，接枝共聚物保留了NVP的内酰胺结构；热重分析表明接枝共聚物的热稳定性得到了增强。接枝共聚物在低接枝率下溶液粘性特征的流变分析表明，其抗高温、抗剪切的能力得到了提高。

Abstract

Simultaneous radiation grafting method (,60,Co γ-rays as the radiation source) was used to prepare xanthan gum-graft-N-vinypyrrolidone (XG-g-NVP), and the influence factors of the grafting degree was preliminarily studied. The structure of the grafted copolymer was characterized by the Fourier-transform infrared spectroscopy (FT-IR) and thermo gravimetric analysis (TGA), and the solution viscosity properties of the grafted copolymer in low grafting rate were studied by rheometer. The results show that the grafting rate increases with absorbed dose and gradually achieve to the balance. The grafting rate reaches maximum when the xanthan gum concentration is 10 g/L or the mass ratio is 10:1 meanwhile the other two factors are in a certain experimental value range. FT-IR figure shows that the grafting reaction occurs in NVP vinyl part and lactam structure is retained. Thermo-gravimetric analysis shows that XG-g-NVP enhanced thermal stability of xanthan gum. The properties of XG-g-NVP solution show that grafting helps to enhance the performance of resisting high temperature and shear strength.
