第13族和第15族元素之间的键是等电子的到碳-碳(CC)键-聚烯烃的主干。聚烯烃可以说是聚合物工业中最重要的一类聚合物，其碳-碳键主链在很大程度上影响着它们的材料性能和应用。此外，它们的化学稳定性和形成它们的合成方法高度依赖于CC取代的性质。除了形式上的类比，碳-碳键和第13族-第15族元素键在极性、稳定性以及通常的几何结构上都有极大的不同。因此，无机聚烯烃可以提供全新的性能；它们需要独特的合成和形成具有独特的反应机理。本章介绍了聚烯烃的第13族-第15族元素类似物；首先是主链中的杂元素，其次是侧链中的杂元素。主要焦点将放在硼-氮(BN)和硼-磷(BP)取代的聚合物上，因为在聚合物的背景下，其他第13族-第15族元素组合仍然非常罕见。
Bonds between group 13 and group 15 elements are isoelectronic to carbon–carbon (CC) bonds – the backbone of polyolefins. Polyolefins are arguably the most important class of polymers in the polymer industry and their carbon–carbon bond backbone influences their materials properties and thus applications to a large extent. Also, their chemical stability and the synthetic methods by which they can be formed are highly dependent on the nature of the CC replacement. Aside from the formal analogy, carbon–carbon bonds and group 13–group 15 element bonds are extremely different in polarity, stability, and often also geometry. Therefore, inorganic polyolefins can offer completely new properties; they require unique syntheses and form with unique reaction mechanisms. This chapter describes group 13–group 15 element analogs of polyolefins; first with the heteroelements in the backbone and secondly with heteroelements in the side chain. The main focus will be placed on boron–nitrogen (BN) and boron–phosphorus (BP) substituted polymers, because other group 13 group–group 15 element combinations are still very rare in the context of polymers.
