摘要:

在硅化學領域中，聚硅氧烷的半無機特性使其在生產與生活中的應用受到了廣泛關注，為滿足聚硅氧烷在基材應用中的特殊需求，單活性官能團封端的聚硅氧烷在常見雙封端聚硅氧烷的基礎上得到發展，并在越來越多的領域中得到應用。與雙封端聚硅氧烷相比，單活性官能團封端的聚硅氧烷的一個鏈端為具有化學惰性的官能團，另一鏈端為可參與化學反應的活性官能團，該活性官能團的活性位點可與其他單體或者含有活性基團的有機聚合物、無機物或硅系化合物進行接枝或者共聚反應，形成嵌段或者接枝改性的硅氧烷共聚物，此類反應不僅可以提高聚硅氧烷的力學性能，而且還可以將聚硅氧烷的優異特性與其他聚合物的特性結合，使得單封端聚硅氧烷在涂料、與其他物質復配等方面擁有更好的優勢。根據官能團的不同，對單活性官能團封端的聚硅氧烷進行了分類，綜述了單活性官能團封端聚硅氧烷的研究進展和應用領域，并對單活性官能團封端的聚硅氧烷的發展趨勢進行了展望。

Abstract:

In the field of silicon chemistry, polysiloxanes have semi-inorganic properties, which have attracted wide attention in production and life. In order to meet the special needs of polysiloxane in application of basic materials, single terminated polysiloxanes are developed on the basis of common double terminated polysiloxanes and used in more and more fields. Compared with double terminated polysiloxane, in single-active functional group terminated polysiloxane molecular, one of its terminal groups is a chemically inert group, while the other is an active functional group that can participate in numerous chemical reactions, and the active reaction sites are used to graft or copolymerize with other monomers or organic polymers, inorganic substances or silicon compounds containing active groups to form block or graft-modified siloxane copolymers, which can not only improve the mechanical properties of polysiloxane, but also combine the excellent properties of polysiloxane with those of other polymers. It makes single terminated polysiloxane gain better advantages in coatings, compounding with other substances and so on. According to the difference of functional groups, single-active functional group terminated polysiloxanes are classified in this manuscript, and the research progress and application fields of single-active functional group terminated polysiloxanes are briefly reviewed. The prospects of single-active functional group terminated polysiloxanes are also provided.
