摘　　要：本文采用丙烯酸甲酯（ＭＡ）、丙烯酸乙酯（ＥＡ）和丙烯酸丁酯（ＢＡ）．用铈离子引发将其与罗布麻纤维接枝共聚。结果表明：当［Ｃｅ４＋］为１０×１０－２ｍｏｌ／Ｌ、［Ｈ＋］为８×１０－２ｍｏｌ／Ｌ、［Ｍｏ］为１２×１０－２ｍｏｌ／Ｌ、４０℃反应３小时可得最大接枝率。在本文实验条件下，单体反应活性顺序为ＭＡ＞ＢＡ＞ＥＡ。Graft copolymerizations of methyl acrylate (MA). ethyl acrylate (EA) and butyl acrylate (BA) onto apocynum fibre using Ce (Ⅳ) system were carried out in heterogeneous system respectively. The optimum graft conditions were determined in our research. The maximum grafting percentage was abtained at [Ce4+] of 10×10-3 mol/L, [H+] of 8 ×10-2 mol/L, [Mo] of 12× 10-2 mol/L. 40℃, 3hrs. In the condition. the graft reactivity of these vinyl monomers follows the trend MA>BA>EA.
