摘要
含硅氧基团的聚氨酯是一种本质阻燃高聚物，它在受强热和暴露于火中时，表面可形成连续的、抗氧化的硅酸盐保护层而具有优良的阻燃作用。当在这类聚氨酯中引入卤素时（如合成时以合溴多元醇为扩链剂），则阻燃效果尤佳。本文综述了硅氧聚氨酯的特性、合成路线及阻燃性能。
Polyurethane containing silicone is one of the instinct flame retardant polymers. When strongly heated ofexposed fo a fire, a continuous and oxidation-resistant layer can be formed on the surface of this kind of polymers, and this layerimparts flame retardancy to the base polymers.If halogen is introduced into the polyurethane (for example, using brominatedpolyols as chain extenders), flame retardancy can further be improved. This paper reviews the characteristics, synthetic routesand flame retardancy of polyurethanes containing silicone groups.
