  Novel polymer polyols based on halogenated aromatic monomers such as tribromostyrene give polyurethane foams with improved flame retardant properties. For example, replacing conventional SAN polymer polyols with tribromostyrene (TBS)/acrylonitrile polymer polyols allows the preparation of polyurethane foams passing British Standard 5852, Part 2, Ignition Source 5 Combustion Test and having better ASTM E-906 values without the need for solid fillers such as melamine or aluminum trihydrate, although these and other flame retardant additives may be optionally employed as well. Elimination of these fillers also provides other improvements such as superior strength and better compression set properties. The TBS dispersions may also be used in conjunction with melamine to eliminate the need for liquid fire retardant additives.

  基于卤代芳香族单体（如三溴苯乙烯）的新型聚合物多元醇可使聚氨酯泡沫的阻燃性能得到改善。例如，用三溴苯乙烯（TBS）/丙烯腈聚合物多元醇取代传统的 SAN 聚合物多元醇，可以制备出通过英国标准 5852 第 2 部分点火源 5 燃烧测试的聚氨酯泡沫，并且具有更好的 ASTM E-906 值，而无需使用三聚氰胺或三水铝等固体填充剂，尽管也可以选择使用这些填充剂和其他阻燃添加剂。不使用这些填料还能带来其他方面的改进，如更高的强度和更好的压缩永久变形性能。TBS 分散体还可与三聚氰胺一起使用，从而无需使用液体阻燃添加剂。
