1、南昌航空大学科技学院学士学位论文间规聚苯乙烯改性研究进展学生姓名：陈东东 班级：0881021指导老师：钟卫摘要：间规聚苯乙烯（sPS）是用茂金属催化剂合成出来的一种新型结晶聚合物。与通用聚苯乙烯相比，具有许多优良的特性：(1)sPS具有熔点高，约270；(2)结晶度高，结晶速率快；(3)耐热性好、耐化学行以及尺寸稳定性好和优良的电气性能。其应用领域非常之广泛，在汽车工业，膜材料，食用容器，电子，电器等领域具有广阔的应用前景。但是sPS的脆性较大，而且分子中缺少极性基团，因此，改善sPS的抗冲击性能，提高其极性一直是广大科技工作者致力解决的课题。随着人们的对sPS的深入研究，新的特殊应用领域还
2、在不断的开拓中，因此具有广泛的应用前景，被看作是复兴苯乙烯行业的希望。同时，其单体苯乙烯便宜易得，sPS产品的利润可观，目前sPS的价格在2.5-4.0万元/吨左右。价格相比昂贵的氟塑料具有很大的优势。本综述，致力于对sPS国内外的最新改性的研究进展，试图能通过查阅大量文献大概的描绘出sPS改性发展的各个阶段所取得的进展。本文详细的描述了各种改性方法，从传统的化学改性，接枝改性，嵌段共聚，共混改性等等，到时下研究比较热的小分子单体改性，以及新兴的纳米改性等。希望通过本文对各种文献的总结，能够对sPS的应用以及未来的改性研究方向做一个概括。并最终使sPS的研究成果服务于国民经济的发展。关键词：间

Which has been prepared by metallocence catalysts .Compared with the general polystyrene，sPS
4、has many excellent properties, such as high melting point (about270)，high degree of crystallinity and rapid crystallization rate, excellent chemical and heating resistance along with its stablity in dimension and excellent properties in electricity，which make sPS an attractive engineer polymers and
5、have been used in many regions，such as automobile，film and electric circum. But its inherent brittleness and polar group absence in molecules signify -cantly limit some end uses. There are two problems，including its nonpolar and brittleness，to solve . How to improve the polarity and the impact stren
6、gth is crucial to modifications of sPS.With the development of technology, people have more research on sPS. There are some more special regions that sPS can be used .And it is to be thought the hope of the polystyrene. At the same time, styrene monomer is cheaper than other plastics. So it is easie
7、r to have large profit form the sPSs business. Then sPSs cost is just twenty five thousand per ton. Compared with the more expensive fluorine plastics, sPS has more advantages.In this paper, I focused on the latest advance modification research in our country and foreign. And I hope I can describe a
8、n outline of sPSs advanced research in the history by consulting large data. And then I summarized many modification methods, from the traditional methods to the new type, such as: chemical modification, grafting modification,Block copolymerization, blending modifications, and so on. Finally, I hope that through my hard work summarized many literatures I can make a conclusion of sPSs development in the future.
