| 摘 要： | 采用种子乳液聚合法将Ｆｅ２Ｏ３超微粒包覆在苯乙烯／丙烯酸／丙烯酸丁酯（Ｓｔ／ＡＡ／ＢＡ）核－壳型复合共聚物中，形成包覆有无机粒子的有机高分子核－壳型复合微球，从微观的分子尺寸上改变了复合共聚物的性能，并着重研究Ｆｅ２Ｏ３的含量对这种复合共聚物的动态力学性能的影响。结果表明，随着Ｆｅ２Ｏ３含量的增加，复合共聚物的内耗明显增加，刚性显著下降。因而Ｆｅ２Ｏ３加入对复合共聚物有增韧作用，改善了复合共聚物的力学性能。

| Abstract: | By seed mulsion polymerization process,Fe 2O 3 nanoparticles were encapsulated in the core-shell composite copolymers of St/AA/BA(styrene/acrylic acid/butyl acrylate)and obtained core-shell composite microspheres that inorganic particles were encapsulated in the organic macromolecules The properties of the composite copolymer were changed on the molecular-sized The influence of Fe 2O 3 nanoparticles on dynamic mechanical properties of composite copolymers were discussed The result showed that with the addition of Fe 2O 3 inorganic particles,the composite copolymers' internal dissipation increase and rigidity decrease obviously Fe 2O 3 nanoparticles improves the strength and mechanical properties of composite copolymer |
