Processes for producing melamine octamolybdates having high thermal stability include a step of reacting molybdenum trioxide and melamine in an acidic aqueous system at a pH of less than or equal to about 4 to form a slurry of the melamine octamolybdate. The resulting melamine octamolybdate can be characterized by a decomposition onset temperature (or a temperature at a weight loss of 1%, or a temperature at a weight loss of 2%) on a thermogravimetric analysis curve of greater than 300° C., and is useful in polymer compositions as a smoke suppressant.
生产具有高热稳定性的八聚钼酸三胺的工艺包括在酸性水系中反应三氧化钼和三胺,pH小于或等于约4,形成八聚钼酸三胺的浆料。所得的八聚钼酸三胺可以通过热重分析曲线上的分解起始温度(或1%重量损失的温度或2%重量损失的温度)大于300°C进行表征,并可用作聚合物组成中的烟雾抑制剂。
