| 摘 要： | 采用溶液聚合法合成了三元丙烯酸酯共聚物（MA／BA／AA）。红外光谱和X－射线衍射分析了共聚物的组成，并探讨了该共聚物与淀粉反应的过程。结果表明，该共聚物在淀粉颗粒上进行自由基接枝共聚反应，反应主要发生在淀粉颗粒的无定形区，改性后的淀粉能够保持原淀粉颗粒的完整结构。

| Abstract: | In this paper, IR a11d X-Ray diffractions were used to investigate the rheological properties of starch modified by acrylic copolymer (methacrylate/butyl acrylate/acrylic acid). It was found that the grafting copolymerization of copolymer ocurred on the starch granula. The modified starch retained its structure as it was before.The rheological properties of the solution of modified starch were tested by Brabender viscometer. |
